IMPACT OF OUTCOME AMBIGUITY ON SELF‐INSURANCE AND SELF‐PROTECTION: EXPERIMENTAL EVIDENCE

This experimental study examines and compares individual valuations of the two risk reduction mechanisms: self‐insurance and self‐protection in risky versus ambiguous outcome situations. Results confirm that individuals do not perceive these mechanisms differently under risk. Moreover, ambiguity in the outcome (i.e., size of loss) affects valuations weakly, and changing representations of ambiguity do not alter valuation. In general, individuals are found to be ambiguity averse for low sizes of loss and ambiguity neutral for high sizes of loss, regardless of the probability of loss. Finally, no strong support is found for any particular model of ambiguity.     

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.     

EXPERIMENTAL EVIDENCE OF A SUNK‐COST PARADOX: A STUDY OF PRICING BEHAVIOR IN BERTRAND–EDGEWORTH DUOPOLY*

We experimentally test the effect of sunk costs on decision making. In the experiment, subjects play the role of price‐setting duopolists. Both firms have identical costs, including an exogenous sunk cost that varies across sessions over six different values. We observe that the sunk cost has a U‐shaped effect: From low to medium levels, average prices decrease, but from medium to high levels, average prices increase. This effect, which is consistent with loss avoidance, develops quickly and persists throughout the game. A follow‐up experiment confirms the main results of the original experiment.     

大股东制衡、治理战略与信息披露-来自2003年中国上市公司的证据

麦敕勒(Metzler,1949)指出,对大国的进口行业征收关税可能会降低其国内相对价格,因而减少了它在经济中的产量份额。针对这一观点,本文发展了关于国民生产总值(GDP)转换对数函数系统的一个理论模型,并据此估计美国贸易政策对其行业产量份额的影响。通过采用美国及其经济合作与发展组织(OECD)贸易成员国的行业面板数据,并在控制要素禀赋和技术创新对行业产量份额的影响后,得出了在服装和玻璃行业呈现高关税导致低产量份额的经验证据。在控制了由贸易的政治经济因素导致的内生性及运用各类非关税壁垒代替关税作为测量行业保护的工具后,这些发现也同样稳健。因此,本文的贡献在一定程度上弥补了国际贸易中该领域实证研究方面的空白:证明了麦敕勒悖论理论不再只是一种可能性,而的确在服装业中存在。     

核心高管特征与公司成长性关系研究——基于中国沪深两市上市公司数据的经验研究

本文以我国沪深两市2004—2006年的上市公司为样本,从核心高级管理人员的人力资本特征视角,对高管特征与上市公司成长性的关系进行了经验检验。本文发现,在其他条件不变的情况下,上市公司成长性与核心高管的平均年龄、平均任职时间显著相关,而与核心高管平均学历的相关性不显著。进一步的研究还表明,在国有控股公司和非国有控股公司中,核心高管特征与公司成长性的关系具有显著差异。本文的研究有助于深化认知人力资本特征在公司发展过程中的重要地位,对强化核心高管遴选、完善人力资源管理具有积极的借鉴意义。     

THE TIME‐SERIES PROPERTIES OF UK INFLATION: EVIDENCE FROM AGGREGATE AND DISAGGREGATE DATA

This paper contrasts the time‐series properties of aggregate and disaggregate UK inflation. While aggregate inflation is found to be non‐stationary, unit root rejection frequencies are increasing when we use more disaggregate data. Structural break analysis suggests that structural shifts in monetary policy could alter inflation persistence. Additionally, panel evidence indicates that the unit root hypothesis can be rejected for sectoral inflation rates. Finally, we compare the persistence properties of UK inflation, finding statistically significant differences between aggregate and disaggregate series. Our analysis suggests that aggregation matters, which has important implications for econometric analysis and the conduct of monetary policy.     

A COMPARATIVE STUDY OF TRAINING IN THE PRIVATE AND PUBLIC SECTORS: EVIDENCE FROM THE UNITED KINGDOM AND THE UNITED STATES

Formal training programs are one of the main channels through which workers become more productive and experience wage growth. So far, however, most of the results on the effects of employer‐provided training come from studying the training received by private sector workers only. We extend the literature by identifying and comparing the effects of private‐employer‐provided and public‐employer‐provided training in the United States and the United Kingdom. We address this question using two independent data sets from the British Household Panels Surveys and the American National Longitudinal Survey of Youth of 1979. (JEL J24, J31, J40)     

REGULATION AND RISK: A CROSS‐COUNTRY SURVEY OF REGULATED COMPANIES

This paper tests empirically whether regulation characterized by high incentives implies more risk to firms than regulation characterized by low incentives. Using a worldwide panel of 170 regulated companies operating in electricity, gas, water, telecommunication and transportation sectors during the period 1995–2004, I find that different regulatory regimes do not result in different levels of risk to their regulated firms. This result could be driven by a higher level of development of financial markets combined with a sophisticated diversifying behaviour of regulated firms.     

BANK PERFORMANCE,FINANCIAL STABILITY AND MARKET CONCENTRATION: EVIDENCE FROM COOPERATIVE AND NON‐COOPERATIVE BANKS

Relying upon highly territorially disaggregated data taken at labour market areas, the paper explores the relationship between bank performances and financial stability of the banking system taking into account the role of market concentration. The z‐score is used as financial stability indicator, while the performance of financial intermediaries is measured using a parametric method recently developed (Kumbhakar et al. 2014). The empirical evidence shows a positive relationship between bank performance and financial stability and supports the ‘concentration–stability’ view for non‐cooperative banks only when concentration is measured on the whole sample of banks. Differences in the performance–stability nexus seem to depend more on the type of banks rather than different levels of market concentration. Higher market concentration of cooperative banks affects systemic stability by reducing the z‐scores of non‐cooperative banks, supporting the hypothesis that the presence of non‐profit‐maximizing entities can pull down stability of other financial institutions.     

FISCAL DECENTRALIZATION AND ECONOMIC VOLATILITY: EVIDENCE FROM STATE‐LEVEL CROSS‐SECTION DATA OF THE USA*

This paper examines the implications of fiscal decentralization for economic stability. It has been discussed that fiscal decentralization reduces the variance of GDP growth, due to the greater diversification of performance across jurisdictions. We examine this theoretical result using a panel data set of the 50 states of the USA over the period of 1992–1997. We show that the theoretical specification of the production function is supported. We also show a negative significant relationship between fiscal decentralization and economic volatility. The results are robust when we take into account the endogeneity of fiscal decentralization.     

REGIONAL ANTI‐CORRUPTION EFFORT,POLITICAL CONNECTIONS AND FIRM INNOVATION EFFORT: EVIDENCE FROM CHINA

This paper examines how firm characteristics and local anti‐corruption effort moderate the influence of political connections on enterprises’ private R&D investment using data from 2,587 Chinese A‐share listed enterprises. Our results show that the local anti‐corruption institutional environment significantly moderates the strong relationship between political connections and enterprises’ private R&D investment. Firm characteristics (i.e., firm size and firm age) also show a moderating effect on the relationship between political connection and enterprises’ private R&D investment; larger and older enterprises are more likely to have innovative resources and business cooperation partners, and thus are able to reduce their degree of reliance on political connections and government funding. The results of our study suggest the importance of having a transparent and fair institutional environment for enterprise innovation activities.     

ECONOMIC VALUATION OF MORTALITY‐RISK REDUCTION: STATED PREFERENCE ESTIMATES FROM THE UNITED STATES AND CANADA

Two internet‐based surveys were conducted with adults aged 35 to 84–885 respondents in the United States and 641 respondents in Canada—to estimate willingness to pay (WTP) for reducing mortality risks through out‐of‐pocket costs for health‐care programs. All respondents were asked a series of choice questions followed by a payment‐card question. Causes of death included cancer and heart attack. Levels of annual mortality‐risk reduction were 1, 2, and 5 in 10,000. Converted to values of statistical life, results were in the range of $4–5 million (2002 U.S. dollars) for the choice‐question results for a 2‐in‐10,000 annual risk reduction for illness‐related mortality. U.S. and Canadian results were similar. The payment‐card results were about 50% lower than the choice‐question results. WTP to reduce mortality risk was essentially the same for cancer and heart attack. The results showed WTP weakly increasing with age, and no evidence of lower WTP for older adults versus middle‐aged adults. (JEL Q51)     

INVESTMENT BEHAVIOUR,CORPORATE CONTROL,AND PRIVATE BENEFITS OF CONTROL: EVIDENCE FROM A SURVEY OF UKRAINIAN FIRMS

We analyse the impact of ownership and corporate control on firms’ investment using the 2001 survey of Yacoub et al. on Ukrainian firms. The model explains investment by output, financial and soft budget constraints, and corporate control (and ownership) categories potentially enjoying private benefits of control. We find that the corporate control model fits better than the ownership model, a negative relationship between state and employee control and firms’ investment, and evidence for the presence of soft budget constraints. A negative relationship between firms’ investment and the relative size of non‐monetary transactions strengthens the conclusion of private benefits of control impacting investment.     

ACTIVITY CHOICES OF INTERNALLY DISPLACED PERSONS AND RETURNEES: QUANTITATIVE SURVEY EVIDENCE FROM POST‐WAR NORTHERN UGANDA

We investigate post‐war economic activity choices of displaced and just‐returned individuals. In particular, the effect of living in an internally displaced persons camp on the choice of economic activities is analysed. Because individuals relocating away from camps may be different from those staying in them, a recursive bivariate probit procedure is used to control for selection on unobservables. The empirical procedure also relies on merging survey data with the micro‐level dataset on conflict events. This allows us to incorporate conflict in the framework, but also to use a bivariate probit procedure to control for endogeneity (selection of households out of camps). This work contributes to literature on household labour allocation and economics of conflict. Results show that residing in a camp has varied effects on the choice of economic activities. Individuals in camps may be more inclined than those who choose to return home, to engage in certain economic activities. One of the key lessons that could be drawn from this paper is that internally displaced persons may possess important livelihood skills that post‐conflict development interventions need to take advantage of, in order to fast‐track recovery.     

DEMAND REDUCTION IN MULTI‐UNIT AUCTIONS WITH VARYING NUMBERS OF BIDDERS: THEORY AND EVIDENCE FROM A FIELD EXPERIMENT*

Recent auction theory and experimental results document strategic demand reduction by bidders in uniform‐price auctions. The present article extends this area of research to consider the effects of varying the number of bidders. Our theoretical model predicts that demand reduction should decrease with an increase in the number of bidders. Considerable demand reduction remains even in the asymptotic limit, although truthful bidding yields profits very close to those of equilibrium play. We experimentally confirm several of our predictions by examining bidding behavior of subjects in an actual marketplace, auctioning dozens of sportscards using both uniform‐price and Vickrey auction formats.     

POST‐PRIVATIZATION OWNERSHIP AND FIRM PERFORMANCE: A LARGE META‐ANALYSIS OF THE TRANSITION LITERATURE

This paper aims to perform a large‐scale meta‐analysis of the relationship between post‐privatization ownership and firm performance in Central and Eastern Europe and the former Soviet Union. Baseline estimation of a meta‐regression model that employs a total of 2,894 estimates drawn from 121 previous studies indicated the superior impact of foreign ownership on firm performance in comparison with state and domestic private entities. Furthermore, the estimation of an extended meta‐regression model that explicitly controls for the idiosyncrasies of transition economies and privatization policies strongly suggested that differences between countries in location, privatization method, and speed of policy implementation strongly influence the link between post‐privatization ownership structure and firm performance. We also found that these factors not only cause a remarkable gap between countries in terms of ex post improvement in firm performance but also significantly affect the interrelationship between foreign investors, domestic outsider owners, and firm managers, and the relative superiority of various domestic outsiders. Conclusive evidence of the harm caused to ex post firm performance by voucher privatization is one of the most noteworthy empirical findings in this paper.     

ASSET POVERTY IN THE UNITED STATES, 1984–99: EVIDENCE FROM THE PANEL STUDY OF INCOME DYNAMICS

Using PSID data for the years 1984–99, we estimate the level and severity of asset poverty. We find that despite a sharp decline in the official poverty rate, the asset poverty rate barely budged over this period. Moreover, the severity of asset poverty increased during this period. The likelihood of being asset-poor decreased for those who are college graduates or married with children, whereas it increased for those who are white, for the unmarried elderly, and for those without a college degree. Lifetime events such as changes in job market, marital and homeownership status are correlated with transitions into and out of asset poverty.     

EVALUATING THE COSTS,QUALITY, AND VALUE FOR MONEY OF INFRASTRUCTURE PUBLIC‐PRIVATE PARTNERSHIPS: A SYSTEMATIC LITERATURE REVIEW

Public?private partnerships (PPPs) are often promoted as a means to lower the costs and increase the quality and value for money (VfM) of public construction and infrastructure projects. While the increasing capital stock of PPPs warrants evaluation of their performance there has until now been limited systematic assessment of PPP versus conventional public procurement. This article contributes to the literature by presenting the findings of a systematic review of empirical peer‐reviewed studies comparing the costs, quality, and/or VfM of infrastructure PPP projects with conventional public procurement. The international literature suggests that PPPs are on average more costly and provide approximately similar VfM as conventional procurement. The number of empirical evaluations is limited, however, and evidence on the quality of infrastructure facilities is particularly scarce. While infrastructure PPPs continue to proliferate, systematic assessment of their performance is warranted to assist policy‐makers in choosing the procurement method that offers best value for taxpayers, users and society.     

A REVISIT TO THE STATIONARITY OF OECD INFLATION: EVIDENCE FROM PANEL UNIT‐ROOT TESTS AND THE COVARIATE POINT OPTIMAL TEST*

This paper re‐examines the stationarity of inflation rates in 19 Organisation for Economic Cooperation and Development countries with the use of cross‐sectional information. We employ the panel unit‐root tests that allow for cross‐sectional dependency and the covariate point optimal test. These tests have high power in common due to the exploitation of cross‐sectional information, and they can assist mutually to draw a concrete conclusion on inflation dynamics for all series in the panel. Our empirical results show that allowing for cross‐sectional dependency rejects the null hypothesis that all series in the panel have a unit root, implying that there is at least one stationary series in the panel. With the help of the results of the covariate test, we can distinguish the panel into a group of stationary and a group of non‐stationary series. For robustness, the two groups of series are re‐confirmed by the panel tests. Our results reveal evidence of mean reversion in inflation for 15 of 19 countries, which is significantly stronger as compared to that obtained by the state‐of‐the‐art univariate unit‐root tests.     

ESTIMATING THE IMPACT OF BEER PRICES ON THE INCIDENCE OF SEXUALLY TRANSMITTED DISEASES: CROSS‐PROVINCE AND TIME SERIES EVIDENCE FROM CANADA

We attempt to contribute to the literature by evaluating the effects of higher beer prices on gonorrhea and chlamydia rates through pooling data across Canadian provinces and over time. Ordinary least squares as well as instrumental variables estimates suggest that higher real beer prices are correlated with a reduction in both gonorrhea and chlamydia rates, with corresponding implied elasticities within a tightly defined interval of (roughly) ?0.7 to ?0.9. However, the increase in real beer prices over the sample period is only responsible for less than a tenth of the decline in gonorrhea rates. (JEL I18)
