HUMAN CAPITAL FORMATION AND CONTINUOUS TRAINING: EVIDENCE FOR EU COUNTRIES

This paper links data on continuous training from the EU Labour Force Survey (LFS) to information on skill levels and earnings from the EU KLEMS growth and productivity accounts, to examine the relative magnitudes of continuous workforce training versus human capital formation through the general education system in the European Union. The measurement methodology draws from the literature on measuring intangible investments by firms and sources of growth in an accounting framework. The results suggest that in the EU15 group of countries, intangible investments in continuous training represent just under 2 percent of GDP or about 35 percent of expenditure on general education. The share of GDP accounted for by training is less than a third as large in the new member states. A growth accounting method is employed to show that failure to account for continuous training leads to an underestimate of the impact of human capital on output growth in the EU.     

转型国家初期的经济绩效差异性及分解:一项基于模糊理论的实证研究

如何正确评价转型国家经济绩效一直是转型经济学研究的一个重点。经过研究发现,转型国家初期在不同的转型策略选择下出现了明显的绩效分叉现象,而出现绩效分叉的主要原因可能是生产能力的差异。而在生产能力体系中,投资水平是最重要的。     

COMPARATIVE ANALYSIS OF EXCHANGE RATE APPRECIATION AND AGGREGATE ECONOMIC ACTIVITY: THEORY AND EVIDENCE FROM MIDDLE EASTERN COUNTRIES

The paper examines the effects of exchange rate depreciation on real output and price in a sample of 11 developing countries in the Middle East. The theoretical model decomposes movements in the exchange rate into anticipated and unanticipated components. Unanticipated currency fluctuations determine aggregate demand through exports, imports, and the demand for domestic currency, and determine aggregate supply through the cost of imported intermediate goods. The evidence indicates that the supply channel attributed to anticipated exchange rate appreciation results in limited effects on output growth and price inflation. Consistent with theory's predictions, unanticipated appreciation of the exchange rate appears more significant with varying effects on output growth and price inflation across developing countries.     

CORRUPTION AND ELECTIONS: AN EMPIRICAL STUDY FOR A CROSS-SECTION OF COUNTRIES

In this paper, we study whether voters are more likely to "vote out" a corrupt incumbent than to re-elect him. Specifically, we examine whether they retract their support from political candidates who they think are corrupt by looking at changes in an index of corruption perceptions between the current and the last elections. Our results suggest that corruption in public office is effectively punished by voters. Furthermore, our findings support the idea that both the political system and the democratic experience are important determinants of the voters' reaction and control of corruption; while voters in countries with parliamentary systems or with relatively low levels of democracy react negatively to an increase in corruption, no perceptible effect of this kind was found in countries with mature democracies, and the evidence is inconclusive in the case of countries with presidential systems.     

THE GOVERNANCE CHALLENGES OF SOCIAL ENTERPRISES: EVIDENCE FROM A UK EMPIRICAL STUDY

ABSTRACT:  The social enterprise sector in the UK is going through a period of rapid growth, and is being seen by government as another important vehicle for delivering public services. As a result the issue of public trust in social enterprise is of growing importance. While there is a growing literature on the governance of voluntary and non-profit organizations, with some exceptions (e.g. co-operatives) there has been little research on the governance challenges and support needs of social enterprises. The research reported here aimed to help fill that gap. Based on interviews and focus groups with governance advisers, board members and chief executives it explores the typical governance challenges faced by social enterprises. Based on the research the paper develops a new, empirically-grounded typology of social enterprises based on their origins and development path, and presents findings about some of the governance challenges that are common across the sector and some that are more distinctive to the different types of social enterprise.     

ENDING RESTRICTIONS TO MIGRATION FROM THE NEW EU MEMBER COUNTRIES: SECTORAL TRADE AND REAL WAGE EFFECTS

Most EU-15 countries have kept restrictions to migration from the new member countries but committed to removing them within seven years from the 2004 enlargement. This article predicts the sectoral trade and real wage impact on high-income, mid-income, and low-income members of removing those restrictions, given two extreme scenarios: either all migrants are skilled or all are unskilled. The main effect of skilled migration is the relocation of high-scale economy, skill-intensive industries from mid-income into high-income countries. The main effect of unskilled migration is the relocation of low-scale economy, low skill-intensive industries from low-income into mid-income countries. Both high-income and low-income members would be better off with skilled migration, but those with mid-income would benefit from unskilled migration. ( JEL F1, F15, F22, J31, L6)     

THE IMPACT OF GOVERNMENT EXPENDITURE ON GROWTH: EMPIRICAL EVIDENCE FROM A HETEROGENEOUS PANEL

This paper investigates the impact of government expenditure on growth, in a heterogeneous panel, for a sample of developing countries. Using generalized method of moments techniques, we show that countries with substantial government current expenditure have strong growth effects, which vary considerably across the nations.     

农地市场对耕地零碎化的影响-理论与来自苏浙鲁的经验

农地市场可能是矫正耕地零碎化的一个工具.但是,由于存在较高的交易费用,农户自发交易耕地对耕地零碎化的影响可能是不显著的.此时,村集体介入农地市场可能降低交易费用,促进土地集中和规模经营,从而降低耕地零碎化程度.该文利用2000年苏浙鲁1083个农户的调查数据对以上假说进行了验证.

INFLATION TARGETING AND THE STATIONARITY OF INFLATION: NEW RESULTS FROM AN ESTAR UNIT ROOT TEST

In this paper, we examine the time series properties of inflation in seven countries that have adopted inflation targeting. Unlike previous studies, we utilize a non‐linear mean reverting adjustment mechanism for inflation and we discover that, although deviations of inflation from the target can exhibit a region of non‐stationary behaviour, overall they are stationary indicating successful targeting implementation.     

TEACHER LOCATION CHOICE AND THE DISTRIBUTION OF QUALITY: EVIDENCE FROM NEW YORK CITY

This article studies the distribution of teacher quality measures across the New York City school system. Because teachers are paid along a fixed salary schedule and they have the option to transfer schools, this analysis measures the degree to which environmental factors affect teacher location choice. Both school-based and neighborhood-based effects are measured, and both types are significant. Furthermore, this article finds that the location of the school in relation to the suburban borders is an important determinant of teacher location choice. (JEL I29 , J24 , J61 )     

THE PARTISAN MODEL OF MACROECONOMIC CYCLES: MORE THEORY AND EVIDENCE FOR THE UNITED STATES*

The “Partisan Theory” of macroeconomic policy is based on the idea that political parties typically weight nominal and real economic performance differently, with left-party governments being more inclined than right-party ones to pursue expansive policies designed to yield lower unemployment and higher growth, but running the risk of extra inflation. Given suitable assumptions about the structure of the macroeconomy, partisan models imply a political signal in demand management, output and inflation movements originating with shifts in party control of the government. In this paper I develop and test with postwar US data a revised Partisan model that allows for (i) uncertainty among policy authorities about the sustainable output growth rate and therefore about how aggregate demand expansions will be partitioned between extra output and extra inflation, and (ii) ex-post and projective learning and preference adjustment under such uncertainty. Dynamic numerical analysis of a small, stylized political-economic model based on these extensions of Partisan Theory generates within-sample forecasts that correspond remarkably well to the observed pattern of price, output and nominal spending fluctuations under the parties.     

STOCKS AND DEPRECIATION OF HUMAN CAPITAL: NEW EVIDENCE FROM A PRESENT-VALUE PERSPECTIVE

Responding to a perceived growing interest in human wealth estimates, this paper offers a framework for measuring the aggregate stock of human capital and then implements the procedure for the United States male population age 14 to 75. Unlike previous estimates of human wealth that are based upon historical or resource costs, these estimates measure the capital stock as the discounted resent-value of expected lifetime returns. In the estimation, returns are equated with earnings data from the 1970 U.S. Census 15 percent Public Use Sample for out-of-school males, adjusted for employment and survival probabilities, adjusted for an assumed exogenous growth in future earnings, and discounted at 7.5 percent.
We provide cross-sectional estimates of individual stocks of human capital by age and educational attainment, as well as expected lifetime wealth profiles for individuals by level of education. These individual profiles can be used to obtain direct estimates of age-specific depreciation which suggest human capital is subject to significant and prolonged appreciation before nearly straight-line depreciation begins around middle age. This finding is all the more significant since resource-cost estimates of human capital which must assume a depreciation pattern to obtain stocks have always imposed a much faster rate much sooner.
Finally, an aggregate estimate of the stock of human capital for all males is supplied and its sensitivity to the choice of the discount rate, tax laws, and expected exogenous growth is analyzed. This seemingly-conservative stock estimate is then compared to a much lower resource-cost estimate offered recently by John Kendrick. A discount rate over 20 percent would be needed to equate the two measures. In trying to reconcile the two figures, we raise some new questions about the validity of both approaches for human capital accounting.     

COUNSELING AND MONITORING OF UNEMPLOYED WORKERS: THEORY AND EVIDENCE FROM A CONTROLLED SOCIAL EXPERIMENT*

We investigate the effect of counseling and monitoring on the individual transition rate to employment. We theoretically analyze these policies in a job search model with two search channels and endogenous search effort. In the empirical analysis we use unique administrative and survey data concerning a social experiment with full randomization and compliance. The results do not provide evidence that counseling and monitoring affect the exit rate to work. Monitoring causes a shift from informal to formal job search. We combine our empirical results with the results from our theoretical analysis and the existing empirical literature, to establish a comprehensive analysis of the effectiveness of these policies.     

INTERGOVERNMENTAL GRANTS AND THE POSITIONING OF PRESIDENTIAL PRIMARIES AND CAUCUSES: EMPIRICAL EVIDENCE FROM THE 1992, 1996, AND 2000 ELECTION CYCLES

The present study tests the theory that states can impact the size of the grants they receive (per capita) from the federal government by becoming pivotal players in the federal electoral (primary/caucus) process. That is, by rearranging their presidential primary and caucus dates, states can play an important role in determining the field of candidates for the two major political parties in the United States. States are then likely to be rewarded within the budgetary process at the federal level, which begins with the executive branch. Results from a simultaneous equation system suggest that the impact of the average movement of primaries/caucuses in the sample period (10.36 days closer to 1 January) results in an increase of federal grants of $362 million to $1.2 billion (over a two-year period) for the average state. These results are consistent with the current pattern in the American political process of more front-ended presidential primaries and caucuses.     

TESTING THE THEORY OF MULTITASKING: EVIDENCE FROM A NATURAL FIELD EXPERIMENT IN CHINESE FACTORIES

Using a natural field experiment, we quantify the impact of one‐dimensional performance‐based incentives on incentivized (quantity) and nonincentivized (quality) dimensions of output for factory workers with a flat‐rate or a piece‐rate base salary. In particular, we observe output quality by hiring quality inspectors unbeknownst to the workers. We find that workers trade off quality for quantity, but the effect is statistically significant only for workers under a flat‐rate base salary. This variation in treatment effects is consistent with a simple theoretical model that predicts that when agents are already incented at the margin, the quantity–quality trade‐off resulting from performance pay is less prominent.     

GLOBAL AND DISAGGREGATED MEASURES OF EARNINGS MOBILITY: EVIDENCE FROM FIVE EUROPEAN COUNTRIES

This paper offers the first application of the local approximation method pioneered by Schluter and Trede (2003) for the Shorrocks mobility indices across the earnings distribution for a range of European Countries covering the main European social models: Denmark, Germany, Spain, the UK and Italy in the pre‐accession EU (1994‐2001). This insightful approach allows us to offer a global and disaggregate analysis of mobility as proportionate change in inequality and hence provide the reader with a full set of information to make his/her own judgment about the extent of mobility and country ranking. Specifically, we investigate the degree to which mobility is driven by low or high earners and how this picture changes across three different earnings measures: full‐time full‐year working, adding part‐time working and then part‐year working. Our results draw out some general key facts. First of all the vast bulk of the measured mobility occurs in the tails especially the lower tail with at least half of the index driven by mobility in the bottom earning quintile. Second, in the top 20 percent of the distribution there are few movements of earnings that effect the level of permanent inequality except in Denmark. Third, no country has a clear dominance for mobility across the full earnings distribution but Denmark differs from the other countries with clearly greater mobility in the middle and at the top. Finally, we find that with the exception of Denmark and Italy, mobility does not lead to clear convergence to the mean but rather to points around 0.7‐0.8 and 1.5 to 2 times the mean.
