The asymmetries academic salary theme comparisons fit in the context of topics such as the measurement of productivity, academic labour market, welfare organization and brain drain. From the research of academic positions for each European country, we imagined the standardization of the academic positions into a single European model, according to the bonds of the similarity of roles between the countries that were analysed. The objective of this paper is to demonstrate whether it is possible to design a European model of standard academic positions and salaries and what are the determining factors for differences. This objective was achieved by creating a data set of official data and applied multivariate methodologies: clustering, regression model, ANOVA and inferential statistics. This study proves that in E urope it is not possible to hypothesize a single model of salaries for academics and it demonstrates the reasons.
There are not complex comparative studies on earnings between academics from different countries because they often lack statistical data on this theme. Another reason lies in the institutional diversity of the individual countries.
It’s difficult to generalize wages in 28 different States such as Europeans because bonuses, allowances and supplements cause a change in the wage in relation to the roles, the institution and the countries [
For example: In Italy, the academic salary has one component, the basic salary. In other European States, the salary includes: the basic component, another components and a merit component. Salary is defined as the most common standard for international comparisons regarding pay. Indeed, salary is the reference variable on which the employer (the university) calculates costs and benefits. The sum of the gross salary places the burden on the employer, the university, and is the total cost of the teaching staff. The gross salary is also the basis on which the national government and the citizens regulate each other’s shareholding relationships. Therefore, we will refer to the gross salary in regard to the evaluations.
If you need to evaluate the differences between the wages we can not limit ourselves to conversion of the currency, as we lose that piece of information related to the cost of living. Wages are often analysed using the PPP (Purchasing Power Parity) conversion rate and the Big Mac index. The PPP conversion factor incorporates the cost of living. Therefore, the PPP conversion factor provides a basis for comparing wages in different international contexts. The PPP helps us to overcome the difficulties of comparison generated by the market’s exchange rate, which is unable to reflect the real cost of living in different countries.
In Slovenia, the institutions may determine salaries in accordance with the law concerning institutes of the public sector and two types of collective agreements.
In Finland, there are many systems wages based on the legal status of each institution and the contracts that are entered into as a result of collective agreements.
In the Czech Republic, Estonia, Austria and Liechtenstein, the definition of these scales is the sole responsibility of the institutions.
However, in Sweden, the salaries are defined individually for each employee based on performance, not on the basis of a scale.
In Latvia, the salaries are established by institutions, and their rate should not be lower than the rates set by the central government.
In Luxembourg, the university provides a grid of wages that must then be approved by the Ministry of Higher Education.
In Malta, the university council or the governors, inside the Malta College of Arts, Science and Technology (MCAST), defines gross annual salaries through the Understanding with the Ministry of Education.
In Spain, salaries are established jointly between the State and the institutions for non-employees. In Lithuania, this situation applies to fellows.
In Denmark, wages are exclusively the result of a collective agreement between the Danish confederation, professional associations (Akademikernes Centralorganisation) and the Ministry of Finance. The Netherlands, Sweden and the UK are characterized by a strong decision-making autonomy of their institutions regarding the definition of annual salaries. In Sweden, salaries are determined on an individual basis, after negotiations that occur exclusively at the institutional level. Salaries are then based on a collective agreement, the unions and the Swedish Agency for Government Employees, which represents public employers. All of the salaries are set by the institutions, except that of the Vice-Chancellors (determined by the government).
In most countries, except the French and German Communities of Belgium, Ireland, Sweden and Norway, wages are expected to be premium wages, often based on the length of service and/or the performance of academic staff.
In most countries, the definition process of salary scales (which allows for, beginning from a basic salary minimum, the progression of the teaching staff during their professional career to the maximum salary) is based on national legislation and other official, central documents.
In certain countries (such as Finland, Ireland, Malta, Portugal and Slovenia), the salary scales result from a negotiation between the State and institutions or unions. In the UK, the negotiation of wages occurs through a specific body called the Joint Negotiating Committee for Higher Education Staff (JNCHES). Institutions will agree on the common scales (except for the type of senior staff, the more qualified) and then determine the salaries. These scales are negotiated nationally through the mechanism of the Joint Negotiating Committee for HE Staff (JNCHES). The negotiation occurs between the associations of university and college employers and the various unions involved that represent the staff.
Comparing the salaries of the countries [
The wage conditions (including salary scales, bonuses and gross salary) constitute a basis upon which higher education institutions have the right to intervene, although very often the central level retains important prerogatives on most aspects in many countries.
The objective of this paper is to demonstrate whether it is possible to design a European model of standard academic positions and salaries and what are the determining factors for the differences.
This objective was achieved by studying the bibliography, by creating a data set of official data (see paragraph 3) and developing methodologies through multivariate analysis (see paragraph 4).
Even if convergences are to be observed among the orientations adopted by higher education policies in European countries, they still are characterized by strong national features. One of the most striking national patterns of each system is its academic labor market, salaries, status, recruitment procedures, workloads, career patterns, promotion rules, being very different from one country to another. Nevertheless, specific national academic labor markets are experiencing a common evolution that can be summed up by the emergence of more regulated internal labor markets. At the same time, the qualification of the academic production (knowledge) as a public good is questioned and academic activities rely less on individual autonomy than before [
There are few empirical contributions on the theme of comparison of academic salaries. Despite what mention should be made some interesting contributions on the topic and some attempts to understand the differences in wages between different countries. An empirical attempt is in Greenbaum [
The investigation “Paying the professoriate”, which was created by Philip Altbach and three colleagues from the Center for International Higher Education (Liz Reisberg and Ivan F. Pacheco) [
“Paying the professoriate” is the first comprehensive comparative analysis of faculty salaries, teacher salaries and working conditions. This paper [
The authors of this work highlight the conditions and expectations that characterize the modern academic profession.
The work of the European University Institute by the ACE (Academic Careers Observatory) discusses comparative data on salaries for different academic positions. Here, the main comparison criteria relate to the length of service and academic productivity. For each country that is compared, information is provided regarding: higher education, academic positions, existing recruitment conditions, requirements necessary for career advancement, the number of existing positions, contracts and benefits provided, and gender.
Comparisons of “gender” appear to be the most analysed factor in recent years due to the asymmetry of the gender proportions in the international academic world (Academic Careers Observatory, 2009: Gender Comparisons).
In 2007, Bruegel [
Another aspect that should be mentioned concerns the strong relationship that exists between the level of wages and productivity. One often reads that countries with greater scientific and academic productivity are those that have higher wages. Should be drawn to on this aspect of the study Richard J. Cebula & Franklin G. Mixon Jr. & Mark A. Montez (2013) [
An educated population is a fundamental ingredient for a well functioning democracy and a crucial driver of growth in the modern economy [
From the bibliography generalises the difference between the salaries, but you do not study in relation to the multiple dimensions: the academic role, the level of wealth of a country, variables of context, macroeconomic variables and variables related to the labor contract. Our attempt will overcome this information gap and this is the idea of this paper.
The definition of salary is related to academic positions. We first need to analyse the differences in wages to reclassify academic roles in a European vision and to possibly standardize a single classification model (see
From the research on academic positions for each European country, we have imagined a standardization of the academic positions in a single European mode, according to the similarity of roles between the countries analysed.
The official ministries of education for the States are: Ministère de l’éducationna- tionale de l’enseignementsupérieur et de la recherche for France, Ministerio de Educacion Cultura y Deporte for Spain, the Department for Education for the United Kingdom, and Bundesministeriumfür Bildung, Wissenschaft, Forschung und Technologie for Germany. However, for other States, the main contribution was provided by MORE2 of Brussels [
According to the analysis of the similarity of the roles, we have created a unique model of European roles: PhD; Post Doc; Assistant Professor Part Time; Assistant Professor Part Time; Assistant Professor Full Time; Associate Professor; Full Professor.
Therefore, in relation to the academic role it is possible to imagine a unique model for all EU states. We found many similarities in the roles though with different nomenclatures, but the contract substance similar.
In statistics, two-dimensional analysis of variance (ANOVA two-way) is an extension of one-way ANOVA that examines the influence of different independent variables on a categorical dependent variable. Although one-way ANOVA measures the effect of a significant independent variable, two-way ANOVA is used when there is more than one independent variable and multiple observations for each independent variable. Two-way ANOVA is able to determine not only the main effect of the contributions of each independent variable but also identifies whether there is a significant interaction effect between the independent variables. In our case, the dependent variable is the salary; the independent variables are the 28 States and the four roles of academic PhDs, Researchers, Associate Professors and Full Professors.

To sample the territorial division of Italy in relation to each aspect, according to the hypotheses made and the different types of behaviour of the phenomenon, groups of variables are used individually according to previous indications. Although the factorial weights are obtained from the 55 variables, 10 macro compound indicators represent the object of the successive elaboration using the Cluvar technique. This technique’s objective is the identification of homogeneous groups and the relations between the units (routes) (relations between the individual units and the clusters identified among those variables that have contributed the most to the ties between the units). Particularly, a data table is provided where xij represents the determination of Xj variable per j = 1, ・・・ m on the Ui unities per i = 1, ・・・n. Let Sn,m be the correspondent table of the standardized values and dj be the most opportune distance. The matrices m of distance are determined. The technique of grouping “Cluvar” is used for this objective (further details are provided in [
In particular, the Cluvar technique was adopted with the intent of not only extrapolating the homogeneity and non-homogeneity among territorial units but of emphasizing the aspect of variables that interact in the system and all of the relations among unity groups.
In contrast to classical techniques, Cluvar provides the possibility of determining aggregations among statistic techniques emphasizing both the variables that significantly influence cluster determination and the weight that those have on the aggregation definition.
The use of groups of variables has allowed a thematic analysis of the phenomenon and its articulations on the territory; however, the vision of the groups is a consideration of the single aspects and the events caused by their integration. Often, the accumulation of joint causes generates demonstrations and different behaviours for the usual interpretive models. Regarding this behaviour, further details on the subject can be obtained by applying alternative, but more sophisticated, techniques, for example, the neutral networks (RNA) and the partial last squared (PLS).

The average salary of a PhD in Europe was ?7,459.32. We find the States with wage levels well above the EU average (see
An analysis of the percentage differences compared to European average wage, there are States where the PhD gains twice the European average wage, by contrast, there are countries with huge negative. For the PhD in Europe ten twenty-eight countries are above the European average wage.
The average salary for the position of a European Researcher was ?5,335.08 (see
For associate professors, the average wage in Europe is ?2,232.77 (see
(?9,788.00), Portugal, Sweden and England are always above the average. At the European average are Finland, Germany and Slovenia. However, far from the European average, are the same countries as for the other two positions.
Ultimately, for the Full Professor position, the average wage in Europe is ?3,995.58 (see

vestments in R & D are also the largest, the GDP is higher (see
If we displayed the wages in individual academic positions per country to the indicators of wealth, we observe interesting results.
The simple generalization of the relationship between wages and GDP does not meet our testing for the presence of diversity.
It 'clear that in this relationship of almost linear relationship between GDP and academic salaries there will be countries where more investment in R&D involving higher wages, but this also correlates with the development of wealth.
If we compare the wages in individual academic positions per country to the indicators of wealth, we observe interesting results.
From this vision, we have developed relations between the wage levels and GDP per capita in a single academic role.
The charts provide a representation of how the individual European countries are organized, based on the relation between the academic position and the salary GDP per capita (see
In particular, from reading the charts, countries such as Denmark, Sweden, the UK, and Austria are at the top of the relation between wages and GDP per capita for all of the academic roles. However, in countries with a low GDP, low wages are recorded.
This linear relationship between wages and GDP is strong and is observed for all academic roles (see Figures 6(a)-(d)). The positions of some States are different but the trends remain the same between the roles. Leading countries in this report are the same if you also record the higher wages. These analyses confirm the theories seen in the theoretical framework: the convergence of higher wages and higher productivity.
In addition, the estimate of regressive parameters between the GDP per capita and the wages for academic roles shows that the wages will grow, on average, by one point
per capita GDP; wages rise by an average of ?800 in each country. In particular, this report shows that there is more growth in the role of Associate Professor, by EUR 1923, on average. The wage growth for a PhD is ?892; for the role of researcher, it is EUR 1754, and for a full Professor, it is 1817 euro (see
The techniques adopted to provide an analysis of the asymmetries at the salary levels are sufficiently representative. The vision of an asymmetric phenomenon can take on the character of duality or patchiness.
Through a clustering model that weighs the links between the factors (coded with 1 = PhD; 2 = researcher; 3 = associate professor; and 4 = full professor) of similarity, it is possible to reconstruct a more precise asymmetry. The results obtained lead to five different clusters.

This type of graphical representation provides a clear picture of the disproportions
that exists intra-Europe between countries and of the aggregation factors that configure homogeneity. From this, analysis emerges assessments regarding academic-related salary differentials between different types of contracts, with the indicators of wealth per capita, with the indices of well-being and with both academic positions.
In addition to measuring academic salary, we asked ourselves what factors can cause these differences in academic payrolls. We considered variables of context, macroeconomic variables and variables related to the labour contract; the variables for each European country follow:
X0 = average annual wage-average wage weighted more than the weight of the roles.
X1 = Load students/teachers-this is one of many indicators of the workload of researchers and teachers.
X2 = HID index on the economic well-being of a country.
X3 = HSID-complex indicators on the economic well-being of a country.
X4 = Benefit Income-this is an indicator based on the employment contract of each country analysed. It is that portion of the salary related to the presence or absence (dummy) of productivity bonuses or to the achievement of specific objectives by academic role.
X5 = Objective criteria in the career roles-we considered the presence or absence (dummy) of objective criteria in the evaluation system on the stages of progress in the career roles. We consider this an index of the assessment of the merit-based bonus system.
X6 = Number of publications-indicator of a further aspect of the productivity of teachers.
X7 = Teachers with less than forty years-indicator of the average time to achieve the roles of the teacher. For us, it represents an indicator of the assessment of the speed of access to higher academic positions.
X8 = Quote R&D-an indicator of the amount of financial resources allocated to each country for scientific research.

-The average annual salary in the EU countries increases with the economic well- being of the country, and it is positively correlated to the index, HSID (ρ = 0.389; p-value = 0.041).
-Countries in which they are granted benefits for productivity register higher wages; the correlation is positive (ρ = 0.518; p-value = 0.005).
-The correlation is positive between the merit award system and the level of wages (ρ = 0.723; p-value = 0.000).
-The relation between the amount of financial resources for research and development is positive for the wage level (ρ = 0.463; p-value = 0.013).
By refining the analysis model, we obtain estimate of the extent of the impact of the factors analysed and the average wage in European countries.
Also these results confirm the initial theory. Higher wages generate higher productivity. Higher wages generate economic prosperity and high employment and a better organizational climate. These relationships are biunivocal and not univocal. It means that there is a relationship of reciprocity.
We used a regression model that is generalized for dummies.

The results of the regressive coefficients provide the following information:
one additional point of economic well-being (HSID) inside on average salary of 57,735 Euros; States with labour contracts that provide benefits or productivity bonuses have an impact on the average salary of EUR 1,237,091; the presence of meritocratic criteria on the State of academic positions produces average wages above 18 thousand euro. Finally, a percentage point higher in the share of research and development has an average salary impact of 97,037 Euro.
The regressive parameters represent the measure of the average change that exists among the analyzed factors and the salary level of a State. This analysis model has possible to identify and estimate the factors statistically significant on wages.
The complex of calculations performed provides a representation of various aspects of wage asymmetry in Europe:
-It describes the wage differences between countries for different roles;
-It measures the relationship between the wage and the wealth of a State;
-Verify the composition of the clusters and in relation to which roles are realized the similarity groups;
-It calculates the relationships between some of the economic factors, the environment and contract with the salary;
-Estimate the extent of the impact of the most significant factors statistically wages of European States.
European academic labor markets are experiencing many changes aiming at similar objectives: the establishment of better regulated internal labor markets and the affirmed role of the university level in the management of the newly introduced incentive mechanisms. This general trend carries with it comparable implications. The presence in Europe of an academic systems salary, which is clustered into five groups, certainly limits the European vision of the academic system; in addition, the influence of factors characterizing each country or each group confirms the assumption.
These differences can be attributed to local context factors, contractual factors and factors such as economic well-being.
These three main systems interact strongly with the level of wages in Europe; they exert a positive influence on the average wage.
With this study we can not support the initial hypothesis of this paper. In Europe it is not possible to hypothesize a single model of salaries for academics.
The policy that should be adopted imagines a unified European wage model. This policy should standardize plans for funding research, identifying relationships with businesses and the territory, monitoring the academic productivity, and developing a single contract system and an equal in value related to the GDP of each country.
Complex and large policies do not suggest possibilities for the development of a unique academic model wage.
Our attempt to study the diversity and wage determinants leads us to these conclusions, which have enabled us to provide a broad understanding of the phenomena studied and the reasons for refusal.
