Returns to Human Capital under the Communist Wage Grid and During the Transition to a Market Economy

Under communism, workers had their wages set according to a centrally-determined wage grid. In this paper we use new micro data on men to estimate returns to human capital under the communist wage grid and during the transition to a market economy. We use data from the Czech Republic because it is a leading transition economy in which the communist grid remained intact until the very end of the communist regime. We demonstrate that for decades the communist wage grid maintained extremely low rate of return on education, but that the return increased dramatically and equally in all ownership categories of firms during the transition. Our estimates also indicate that men's wage-experience profile was concave in both regimes and on average it did not change from the communist to the transition period. However, the de novo private firms display a more concave profile than SOEs and public administration. Contrary to earlier studies, we show that men's inter-industry wage structure changed substantially between 1989 and 1996.http://deepblue.lib.umich.edu/bitstream/2027.42/39656/3/wp272.pd

Searches for leptoquark production and compositeness at the Tevatron

Recent searches for leptoquark production and compositeness in p-anti-p collisions at sqrt{s}=1.96 TeV are presented using data samples with integrated luminosities up to 4 fb^{-1} recorded with the D0 and CDF detectors at the Tevatron collider.Comment: Invited talk at European Physical Society Europhysics Conference on High Energy Physics, EPS-HEP 2009, Krakow, Polan

Visual identification by signature tracking

We propose a new camera-based biometric: visual signature identification. We discuss the importance of the parameterization of the signatures in order to achieve good classification results, independently of variations in the position of the camera with respect to the writing surface. We show that affine arc-length parameterization performs better than conventional time and Euclidean arc-length ones. We find that the system verification performance is better than 4 percent error on skilled forgeries and 1 percent error on random forgeries, and that its recognition performance is better than 1 percent error rate, comparable to the best camera-based biometrics

The Economic Effects of the Protestant Reformation: Testing the Weber Hypothesis in the German Lands

Following Max Weber, many theories have hypothesized that Protestantism should have favored economic development. With its religious heterogeneity, the Holy Roman Empire presents an ideal testing ground for this hypothesis. Using population figures of 272 cities in the years 1300–1900, I find no effects of Protestantism on economic growth. The finding is precisely estimated, robust to the inclusion of various controls, and does not depend on data selection or small sample size. Protestantism has no effect when interacted with other likely determinants of economic development. Instrumental variables estimates, considering the potential endogeneity of religious choice, are similar to the OLS results

Unemployment and Worker-Firm Matching Theory and Evidence from East and West Europe

The paper tests three hypotheses about the causes of unemployment in the Central-East European transition economies and in a benchmark market economy (Western part of Germany). The first hypothesis (H1) is that unemployment is caused by inefficient matching. Hypothesis 2 (H2) is that unemployment is caused by low demand. Hypothesis 3 (H3) is that restructuring is at work. Our estimates suggest that the west and east German parts of Germany, Czech Republic and Slovakia are consistent with H2 and H3. Hungary provides limited support to all three hypotheses. Poland is consistent with H1. The economies in question hence contain one broad group of countries and one or two special cases. The group comprises the Czech Republic, Hungary, Slovak Republic and (possibly) East Germany. These countries resemble West Germany in that they display increasing returns to scale in matching and unemployment appears to be driven by restructuring and low demand. The East German case is complex because of its major active labor market policies and a negative trend in efficiency in matching. In some sense, East Germany resembles more Poland, which in addition to restructuring and low demand for labor appears to suffer from a structural mismatch reflected in relatively low returns to scale in matching. Finally, our data provide evidence that goes counter to one of the main predictions of the theories of transition, namely that the turnover (inflow) rate in the transition countries would rise dramatically at the start of the transition, be temporarily very high and gradually decline and approach the level observed in otherwise similar market economies such as West Germany.access to information; Active Employment; Active Employment Policy; active labor; active labor market; active labor market policies; active labor market programs; Active Labour; Active Labour Market

Microfoundations of the Wage Inflation in the Czech Republic

We investigate whether microfoundations might increase the predictive power of macroeconomic models of wage inflation. By comparing past predictions to observed values, we find that the Phillips curve with the average unemployment rate in districts with prevalently low unemployment rates delivers more accurate predictions of aggregated wage inflation than the Phillips curve with the overall unemployment rate. The identification of specific groups of districts is based on our estimates of the wage curve at the regional level, i.e. the relationship between the regional level of wages and regional unemployment. Real wages adjust to changes in local unemployment in districts with low unemployment rates, a low share of public sector employment, and for the short-term unemployed. On the other hand, the welfare system might represent a floor preventing downward wage adjustments in districts with high unemployment rates and for the long-term unemployed. In the public sector, wages are negotiated at the economy-wide level, while the variance in regional unemployment does not play a role.Panel data, partial adjustment model, Phillips curve, unemployment, wage curve.

Responses of Private and Public Schools to Voucher Funding:The Czech and Hungarian Experience

A state monopoly in schooling followed the collapse of communism in Central Europe. The centrally planned system was abandoned. Systems comparable with educational voucher scheme, also known as school choice system, were introduced in the Czech Republic and Hungary in the early 1990s. The newly established system of school financing allocates public funds according to the number of students enrolled in a school. Accredited non-state schools, private and religious, are also eligible for public subsidies. The scope and the form of these reforms represent a unique opportunity to test conflicting hypotheses of proponents and opponents of the voucher scheme. In this empirical analysis, we test fundamental theoretical predictions of the voucher model. Specifically, we test: i) whether non-state schools are established at locations where the supply of educational opportunities provided by state schools is low or of low quality, ii) whether state and non-state schools in such a system respond to changes in demand for education, and iii) whether state schools respond to competition from non-state schools. We use detailed school level data on the whole population of schools and data on regional conditions. In our econometric model we estimate education value added, instead of relying on absolute quality of school graduates. We find that non-state school emerge at locations with excess demand and lower quality state schools. We also find that greater competition from non-state schools creates incentives for state schools with the result that state schools slightly improve the quality of educational inputs used and significantly improve their output, quality of graduates. As concerns the technical schools, we find that non-state schools react to regional labor market conditions in terms of technical branch premium and unemployment rate. We do not find such reactions to market signals by state schools. We introduce this analysis with a review of non-state schools' development in the Czech Republic and Hungary during the 1990s.educational finance; government expenditures and education; occupational choice; labor productivity

Worker-firm Matching and Unemployment in Transition to a Market

In this paper we compare the nature and determinants of outflows from unemployment in the case of the Czech and Slovak Republics which in early 1990’s experienced a process close to a controlled experiment. Overall, our study suggests that the exceptionally low unemployment rate in the Czech Republic as compared to Slovakia and the other Central and East European economies has been brought about principally by (1) a rapid increase in vacancies along with unemployment, resulting in a balanced unemployment-vacancy situation at the aggregate as well as district level, (2) a major part played by vacancies and the newly unemployed in the outflow from unemployment, (3) a matching process with strongly increasing returns to scale throughout (rather than only in parts of) the transition period, and (4) ability to keep the long term unemployed at relatively low levels. Using the framework of matching functions we find that in many years the usual Cobb-Douglas specification and the hypothesis of constant returns to scale are rejected. A translog matching function with weak separability between the existing and newly unemployed is found to be the functional form best supported by the data. Our theoretical analysis also indicates that by not adjusting data for the varying size of districts or regions, previous studies may have generated estimates of the returns to scale of the matching function that were biased toward unity.
