Does labour supply respond to a flat tax?

We exploit the exogenous change in marginal tax rates created by the Russian flat tax reform of 2001 to identify the effect of taxes on the labour supply of men and women. We apply a weighted difference‐in‐difference regression approach and instrumental variables to estimate labour supply functions using a panel dataset. The mean regression results indicate that the tax reform led to a statistically significant increase in hours of work for men but had no effect on work hours for women. However, we find a positive response to tax changes in both tails of the female work hour distribution. We also find that the reform increased the probability of finding a job among both men and women. Despite significant variation in individual responses, the aggregate labour supply elasticities are trivial. This suggests that reform‐induced changes in labour supply are an unlikely explanation for the amplified personal income tax revenues that followed the reform.     

The determinants of Latin American exchange rate regimes

The experience of the last thirty years suggests that a wide range of factors affects policymakers’ choice of exchange rate regime. The initial explanation was that changes in the international sphere dominated domestic policies and strongly influenced how governments decided among the trade-offs. More recently, domestic political factors’ influence on the choice of exchange rate regimes have been emphasized, providing detailed and rich insights into the dynamics of the choice. Neither approach has been entirely successful. Both internal and external factors must be taken into account. This article builds on previous empirical work and takes into account domestic and international influences on the choice of exchange rate regimes in Latin America between 1964 and 1996. In addition, we highlight a variety of ‘interactions’, choices of economic policy that are affected by both national and international pressures and that, in turn, influence the choice of exchange rate regime. The empirical model uses multinomial ordered logit analysis to determine the factors in exchange rate determination and to compare the explanatory of the models with and without the interaction variables.     

Performance Manipulation and Fund Flow: Evidence from China

In this paper, we assess the relation between fund flow and fund returns in China's open-ended fund industry. Analyzing quarterly data from the period January 2005-December 2012, we construct a simultaneous equation model that captures the endogeneity of current and past returns and flows and find that contemporaneous returns have a key role in determining fund flows. We then estimate the fund performance "manipulation degree" to further investigate the performance manipulation effect on fund flows. We find that manipulated funds can attract an additional flow of money and that, notably, individual rather than institutional investors are more likely to be deceived by manipulative behavior.     

股权结构与公司投资效率间的动态关系—基于动态内生性的经验研究

以2002-2011年716家上市公司为样本,在动态内生性的框架下,运用动态面板的System GMM估计方法,同时考虑三种内生性,以动态性的视角研究股权结构与公司投资效率间的关系。得到以下结论：（1）不仅当期股权结构对当期公司非效率投资有影响,而且前期股权结构也对当期公司非效率投资有影响;（2）股权结构对公司非效率投资有长期影响;（3）前期公司非效率投资对当期股权结构有反馈效应;（4）股权结构与公司非效率投资间存在动态内生性。     

Business Cycle Synchronization in the Enlarged EU

This paper analyzes the synchronization of business cycles between new and old EU members using various measures. The main findings are that Hungary, Poland and Slovenia have achieved high degree of synchronization for GDP, industry and exports, but not for consumption and services. The other CEECs have achieved less or no synchronization. There has been significant increase in synchronization of GDP and its major components within EMU. This lends support to the argument of OCA endogeneity but there is also evidence of a world cycle. The consumption-correlation puzzle remains, but its magnitude has greatly diminished in the EMU members.     

Relationships between Technical Efficiency and Financial Management for Czech Republic Farms

This paper provides the first analysis of the relationship between farm financial structure and technical efficiency in Central and Eastern European farming during the transition to a market economy. First, technical efficiency scores for a sample of Czech farms are computed with data envelopment analysis, accounting for sampling variability by using the Simar and Wilson bootstrapping procedure. The confidence intervals show that corporate livestock farms are the most homogenous in terms of technical efficiency. Second, a Tobit model is applied for the investigation of factors, including financial considerations, which influence the variation in technical efficiency. The potential endogeneity of the financial variables in the explanation of efficiency is examined, following Smith and Blundell. The Amemiya estimator is used for those cases which are revealed as endogenous. The analysis indicates substantial differences in the way in which the different management structures are treated by lenders. De novo, individual farms are subject to stringent evaluation of their loan applications, which is not the case for the successors of the former collective and state farms.     

Board Share‐Ownership and Takeover Performance

Abstract:   We investigate the relation between takeover performance and board share‐ownership in the acquiring company for a sample of 363 UK takeovers completed in the period 1985–96. In investigating this relationship we pay particular attention to the composition of board shareholdings as well as their size. Thus, in addition to the analysis of total board holdings, we analyse the separate impact of CEO shareholdings and of the pattern of non‐executive and executive holdings within the board. In addition to our detailed examination of board holdings we assess the impact of non‐board holdings. Our analysis controls for a number of non‐shareholding constraints on discretionary director behaviour and for a variety of other influences on takeover outcomes including: the means of payment; acquirer size and market to book value; the relative size of the acquirer and the target; the nature of the bid in terms of hostility and industrial direction; and the pre‐takeover performance of the acquiring company. We assess performance in terms of announcement returns, long run share returns and a portfolio of accounting measures. We find evidence that overall board ownership has a strong positive impact on long run share returns and a weak positive impact on operating performance. However, much stronger effects are found when the overall board measure is split into CEO, executive, and non‐executive directors. We find strong evidence of a positive relation between takeover performance and CEO ownership, which holds for both long run returns and operating performance measures. This finding is robust to controlling for other factors that determine takeover performance and holds in a two stage least squares framework that controls for endogeneity effects. Shareholdings of other executive directors, non‐executive directors, and non‐board holdings are found to have no significant effect on takeover performance.     

Executive pay and performance: the moderating effect of CEO power and governance structure

This paper examines the crucial question of whether chief executive officer (CEO) power and corporate governance (CG) structure can moderate the pay-for-performance sensitivity (PPS) using a large up-to-date South African data-set. Our findings are threefold. First, when direct links between executive pay and performance are examined, we find a positive, but relatively small PPS. Second, our results show that in a context of concentrated ownership and weak board structures; the second-tier agency conflict (director monitoring power and opportunism) is stronger than the first-tier agency problem (CEO power and self-interest). Third, additional analysis suggests that CEO power and CG structure have a moderating effect on the PPS. Specifically, we find that the PPS is higher in firms with more reputable, founding and shareholding CEOs, higher ownership by directors and institutions, and independent nomination and remuneration committees, but lower in firms with larger boards, more powerful and long-tenured CEOs. Overall, our evidence sheds new important theoretical and empirical insights on explaining the PPS with specific focus on the predictions of the optimal contracting and managerial power hypotheses. The findings are generally robust across a raft of econometric models that control for different types of endogeneities, pay, and performance proxies.     

Sample selection bias and Heckman models in strategic management research

Research summary: The use of Heckman models by strategy scholars to resolve sample selection bias has increased by more than 700 percent over the last decade, yet significant inconsistencies exist in how they have applied and interpreted these models. In view of these differences, we explore the drivers of sample selection bias and review how Heckman models alleviate it. We demonstrate three important findings for scholars seeking to use Heckman models: First, the independent variable of interest must be a significant predictor in the first stage of a model for sample selection bias to exist. Second, the significance of lambda alone does not indicate sample selection bias. Finally, Heckman models account for sample‐induced endogeneity, but are not effective when other sources of endogeneity are present. Managerial summary: When nonrandom samples are used to test statistical relationships, sample selection bias can lead researchers to flawed conclusions that can, in turn, negatively impact managerial decision‐making. We examine the use of Heckman models, which were designed to resolve sample selection bias, in strategic management research and highlight conditions when sample selection bias is present as well as when it is not. We also distinguish sample selection bias, a form of omitted variable (OV) bias, from more traditional OV bias, emphasizing that it is possible for models to have sample selection bias, traditional OV bias, or both. Accurately identifying the type(s) of OV bias present is essential to effectively correcting it. We close with several recommendations to improve practice surrounding the use of Heckman models.

财政转移支付与地方政府支出行为——基于中国地市面板数据的实证分析

本文运用一个简单的理论框架分析了转移支付对地方政府财政支出行为的影响效应,并实证检验了省以下政府间财政转移支付对地方政府财政支出行为的影响效应。分析结果表明:一般性转移支付与地方财政支出之间存在显著的替代效应,而专项转移支付与地方政府财政支出之间存在着显著的互补效应,并且地方政府并不存在反应过度问题。本文的政策建议是:从短期来看,中央政府通过一般性转移支付方式可以有效降低基层政府的财政债务负担,通过专项转移支付可以有效提高基层政府公共服务的供给数量和质量;从长期来看,应进一步完善分税格局,给予地方政府(特别是基层政府)更多与其事权相匹配的税权能力。
