In this article, we analyse public sector efficiency in the new member states of the EU compared to that in emerging markets. After a conceptual discussion of expenditure efficiency measurement, we compute efficiency scores and rankings by applying a range of measurement techniques. The study finds that expenditure efficiency across new EU member states is rather diverse especially as compared to the group of top performing emerging markets in Asia. Econometric analysis shows that higher income, civil service competence and education levels as well as the security of property rights seem to facilitate the prevention of inefficiencies in the public sector.  相似文献

This paper investigates the relationship between institutions and economic development (output per worker). As in Hall and Jones (1999), we find that a 1% improvement in institutions (as we measure them) generates on average a 5% increase in output per worker. However, this relationship is not linear and the data have important heterogeneity. Countries with the same value of institutions have different levels of income per worker. We ask whether the “returns to institutions” are the same across countries conditional on the level of institutions. Using quantile regression methods, we show that for countries at the top of the conditional distribution of international incomes, the “returns to institutions” are lower (around 3.8%,) than for countries at the bottom of this distribution (around 6.2%). We show that this result is robust for different model specifications and definitions of institutions. We also provide evidence that, conditional on the level of institutional development, the distribution of output per worker tends to become less disperse as countries improve their institutional framework. In other words, having better institutions is essential in order to close the output-per-worker gap across countries. Finally, we provide the rationale behind the results through a modified version of a Neoclassical Growth Model with time varying wedges, representing policy distortions and institutions.We thank Lee Alston, Roger Koenker, and Stephen L. Parente for helpful discussion, Werner Baer for useful comments, and Chad Jones for facilitating access to the data set. We are also indebted to an anonymous referee and an associate editor for important suggestions that improved the final paper.

In this paper, we conjecture that the weak association between disclosure and cost of equity capital found in the literature (Botosan, 1997) can be caused by the high-level corporate disclosure environment found in the United States. We hypothesize that in low-level corporate disclosure environments the variability in disclosure practices across firms will be larger than in the United States, and, consequently, the marginal effect of voluntary disclosure policies will be higher. Using a newly developed Brazilian Corporate Disclosure Index (BCDI), our results confirm this hypothesis. Disclosure is strongly associated with ex ante cost of equity capital for Brazilian firms. The results are more pronounced for firms with less analyst coverage and low ownership concentration, as expected.  相似文献

Bayesian model averaging (BMA) provides a coherent and systematic mechanism for accounting for model uncertainty. It can be regarded as an direct application of Bayesian inference to the problem of model selection, combined estimation and prediction. BMA produces a straightforward model choice criterion and less risky predictions. However, the application of BMA is not always straightforward, leading to diverse assumptions and situational choices on its different aspects. Despite the widespread application of BMA in the literature, there were not many accounts of these differences and trends besides a few landmark revisions in the late 1990s and early 2000s, therefore not accounting for advancements made in the last decades. In this work, we present an account of these developments through a careful content analysis of 820 articles in BMA published between 1996 and 2016. We also develop a conceptual classification scheme to better describe this vast literature, understand its trends and future directions and provide guidance for the researcher interested in both the application and development of the methodology. The results of the classification scheme and content review are then used to discuss the present and future of the BMA literature.  相似文献

The authors develop and test a model depicting the moderating effects of different types of manager leadership styles on the relationship between salesperson goal orientations (i.e., performance orientation and learning orientation) and performance. The two surveys were set in retail work contexts in Brazil. Results from a multi-level hierarchical analysis demonstrate that (i) transactional leadership strengthens the positive link between learning orientation and sales performance, whereas (ii) transformational leadership weakens the positive association between learning orientation and performance. Our argument for the positive moderating effect of transactional leadership is built upon the path-goal theory and contingent reward mechanism. The justification for the negative effect of transformational leadership involves the follower-dependency logic and overdependence on supervisory cues.  相似文献

This paper studies the effects of cash transfers to the poor on the labor market. This is investigated in a matching model with endogenous labor market participation and job destruction. Depending on their productivity, workers might want to stay in the job, become unemployed, or leave the labor market; in addition, workers out of the labor force might decide to search for a job. Cash transfers are introduced to all agents with income below a given level. Two qualitative results are found: (i) The size of cash transfers has a negative effect on the employment rate, but an ambiguous effect on the unemployment rate; and (ii) the coverage of this welfare program has a positive effect on the employment rate, and an ambiguous effect on the unemployment rate. The numerical simulations also show that: (i) if the government target is to reduce inequality and poverty, the more efficient policy is to increase the level of benefits instead of increasing the eligibility of the program; (ii) compared with a welfare program that condition eligibility to labor market participation, the “unconditional” cash transfer program has a stronger impact on inequality and poverty, but with a reduction in labor market participation and output.  相似文献

We investigate the link between fiscal policy shocks and asset markets. Our results show that spending shocks have: a positive and persistent effect on GDP in the U.S. and in the U.K., while for Germany and Italy, such impact is temporary; a positive and persistent effect on housing prices; a negative effect on stock prices; and mixed effects on the price level. A VAR counter-factual exercise suggests that fiscal shocks play a minor role in the asset markets of the U.S. and Germany, and substantially increase the variability of housing and stock prices in the U.K., while government revenue shocks have increased volatility in Italy.  相似文献

With a new quarterly dataset we estimate a Bayesian Structural Autoregression model and a Fully Simultaneous System approach to analyze the macroeconomic effects of fiscal policy. Results show that positive government spending shocks, in general, have a negative effect on real GDP; lead to “crowding-out” effects of private consumption and investment; have a persistent and positive effect on the price level and a mixed impact on the average financing cost of government debt. Explicitly considering the government debt dynamics in the model is also important. A VAR counter-factual exercise confirms that unexpected positive spending shocks create relevant “crowding-out” effects.  相似文献
