Refining Targeting against Poverty Evidence from Tunisia*

We introduce a new methodology to target direct transfers against poverty. Our method is based on estimation methods that focus on the poor. Using data from Tunisia, we estimate ‘focused’ transfer schemes that highly improve anti‐poverty targeting performances. Post‐transfer poverty can be substantially reduced with the new estimation method. For example, a one‐third reduction in poverty severity from proxy‐means test transfer schemes based on OLS method to focused transfer schemes requires only a few hours of computer work based on methods available on popular statistical packages. Finally, the obtained levels of undercoverage of the poor are particularly low.     

The Impact of Training on Productivity and Wages: Evidence from British Panel Data*

It is standard in the literature on training to use wages as a sufficient statistic for productivity. This paper examines the effects of work‐related training on direct measures of productivity. Using a new panel of British industries 1983–96 and a variety of estimation techniques we find that work‐related training is associated with significantly higher productivity. A 1% point increase in training is associated with an increase in value added per hour of about 0.6% and an increase in hourly wages of about 0.3%. We also show evidence using individual‐level data sets that is suggestive of training externalities.     

The Implications of Trade Credit for Bank Monitoring: Suggestive Evidence from Japan

Firms in modern developed economies borrow from both banks and trade partners. Using Japanese manufacturing data from the 1960s, we estimate the price of trade credit, and explore some of the ways firms choose between the credit and bank loans. We find that firms of all sizes borrow heavily from their trade partners, and at implicit rates that track the explicit rates banks would charge. They borrow from banks when they anticipate needing money for relatively long periods; they turn to trade partners when they face short-term unexpected exigencies. This apparent contrast in the term structures follows, we suggest, from the fundamentally different way bankers and trade partners cut default risk. Because bankers seldom know their borrowers' industries first hand, they rely on formal legal protection (like security interests). Because trade partners know the industry well, they reduce risk by monitoring their borrowers closely instead. Because the costs to creating legal mechanisms are heavily front-loaded, bankers focus on long-term debt; because the costs of monitoring debtors are ongoing, trade creditors do not. Apparently, banks monitor less than we have thought.     

银行监督的动态治理效应分析——基于中国上市公司的经验证据

财务理论与实证研究认为,银行作为企业一个重要的利益相关者,能够对借款人形成积极的治理效应。银行实践中是通过事前监督、事中与事后监督这样一个动态机制来实现其作用的。在区别了银行监督与债权治理、债务治理的基础上,实证分析了银行监督在不同阶段的治理效应。结果表明,银行的事前监督是有效的,这可以极大地降低逆向选择风险,但事中与事后监督呈无效性特点,这说明道德风险的隐患仍然不容忽视。     

The Impact of the Big 8 Mergers on Market Power: Evidence from the Hong Kong Market

This study examines the impact of the Big 8 mergers on market power in an audit market where the merging firms have little presence. Audit fee changes for each merger participating firm are identified and fee changes for several post‐merger years are examined. The pre‐merger differential market power between the merging and non‐merging long‐established Big 8 firms (Price Waterhouse and KPMG Peat Marwick) in Hong Kong provides a unique opportunity to examine whether the mergers could help the merging firms to increase their market power. The results are consistent with the hypotheses that the audit fees of the merging firms were significantly lower than that of the non‐merging, long‐established Big 8 firms before the mergers, but the audit fees of the merged firms increased significantly to a level comparable with that of the latter group after the mergers. In addition, the market share of the merged firms increased significantly after the mergers. However, no association is found between market concentration and market power. Overall, the results show that the Big 8 mergers have helped the merged firms increase their market power and market share in the Hong Kong audit market where they had little presence.     

The Impact of Trade Liberalization on Micro Enterprises: Do Banks Matter? Evidence from Indian Manufacturing

This paper looks at the impact of trade liberalization on micro enterprises with differential access to banks. I use Indian data on rural micro enterprises employing less than ten workers in the manufacturing sector to find that trade liberalization, measured by a fall in the tariff, is associated with a larger increase or a smaller decrease in output, capital–labour ratio and labour productivity in districts with a larger number of bank branches per capita. Evidence is consistent with strong complementarities between trade liberalization effects, and the economic dynamism and access to financial intermediation associated with greater bank presence in the enterprise's location. The study underscores that trade liberalization can be beneficial to micro entrepreneurs under certain conditions and emphasizes reallocation resulting from trade liberalization. The study hence highlights the role for development policy in exploiting gains from trade.     

The Impact of Terrorism on Social Capital: Evidence from the 2015 Charlie Hebdo Paris Shooting

We examine the impact of terrorism on social capital by exploiting variation in the 2014 European Social Survey administration dates coupled with the 2015 Charlie Hebdo attack in Paris, France. Using the difference-in-differences estimator, we find that the attack had a positive, causal impact on the overall level of social capital among French respondents. Further, the effect seems to be driven by an increase in institutional and interpersonal trust, as well as by engagement in social networks. This rise in social capital peaks in the immediate aftermath of the terrorist attack but subsequently decays to pre-attack levels within approximately one month.

The Impact of Multilateral Trade Liberalisation on Economic Development: Some Empirical Evidence

This article examines the impact of multilateral trade policy liberalisation on countries' levels of economic development, proxied by their real per capita income. The study is particularly relevant in the current context of growing rhetoric against international trade, which could fuel domestic protectionism and would likely undermine multilateral trade liberalisation. The analysis has been conducted on a panel data set of 155 countries, over non‐overlapping four‐yearly sub‐periods during 1995–2014. The empirical results suggest strong support for the view that multilateral trade liberalisation promotes economic development. Hence, the rise in unilateral protectionist trade measures around the world would likely endanger the prospects of further multilateral trade liberalisation and ultimately undermine countries' prospects of economic development.     

The Impact of Compulsory Arbitration on Bargaining Behavior: An Experimental Study

A series of experiments compares bargaining behavior under three different settings: no arbitration, conventional and final-offer arbitration. Under no arbitration, disputes with zero payoffs were around 10%, while the pie was equally split in less than half of the cases. Under conventional arbitration – where the arbitrator is free to choose his award – every third negotiation ended in dispute, evidencing a modified chilling effect. Under final-offer arbitration – where the arbitrator must award the bargainers either one of their final offers – there was only a small increase in disputes, while equal splits doubled to 80%. The experiment shows that final-offer arbitration, despite having lower dispute rates, interferes more with bargaining behavior than conventional arbitration, where bargaining behavior is similar to that seen in the no-arbitration treatment. Under final-offer arbitration, negotiators adjust their bargaining strategy on the arbitrator’s expected award.     

The Impact of Degree Duration on Higher Education Participation: Evidence from a Large‐scale Natural Experiment

This paper investigates the effects on enrolment, retention rate and on‐time graduation of a nationwide Bologna Process reform introduced in Italy to establish BAs with a duration of three years, followed by optional second‐tier degrees of two years, in place of single‐tier degrees of four or five years. The analysis exploits exogenous delay of treatment conditions and the unique availability of microdata that cover the universe of the departments. We estimate that the reform boosted first‐year enrolments by 14.5–17.3 percentage points, compared to a counterfactual status of no reform. This enrolment shift was due to participation gains rather than substitution effects, and it is likely to have persisted in the longer term. Moreover, no trade‐off between increased participation and deteriorated retention and on‐time graduation emerged.     

In Support of Trigger Strategies: Experimental Evidence from Two-Person Noncooperative Games

Cooperative equilibria can be supported in a repeated game when players use trigger strategies. This paper tests how well trigger strategies explain behavior in two-person experimental games. Reducing payoffs for choices larger than the Cournot level induces smaller average outputs, behavior generally consistent with trigger strategy models. Reducing payoffs for choices well above the Cournot level will not affect behavior if actions are consistent with a trigger strategy involving longer-lived, less intense punishment phases (the grim-reaper strategy), but would matter for trigger strategies with short-lived but intense punishment phases. Results show that behavior is most consistent with the former.     

Impact of Changes in Consumer Preferences on Sectoral Labour Reallocation: Evidence from the Italian Economy

This study empirically investigates the impact of changes in consumer preferences on labour reallocation across the Italian economic sectors. For this purpose, coherent sectoral time series of consumer preferences and labour units are constructed from Italian national accounts and consumption expenditure data. In line with recent firm‐level evidence, empirical findings indicate a positive and significant effect of preference changes on labour reallocation. Results are robust to several econometric specifications, different procedures to elicit preference changes, as well as the introduction of time‐varying price coefficient and sector‐specific effects of total consumption expenditure.     

Impact of Environmental Performance on Firm Value for Sustainable Investment: Evidence from Large US Firms

This research examines the impact of environmental performance on firm value, applying the event study methodology to Newsweek’s ‘Green Rankings’ announcement of 2012 for large US firms. Specifically, it analyzes the impact of the absolute green score and green rank of firms on their performance in the stock market. We found that investors perceive the announcement as positive news, leading to significant positive standardized cumulative abnormal returns (SCARs). After controlling for industry‐ and firm‐specific effects, we observed that firms with repeated green rankings for enhancing environmental performance showed significantly higher SCARs than those with either reduced or unchanged environmental performance. In addition, the environmental impact score measuring environmental damage from a firm's operational activities was found to be the most influential factor in improving the firm's value. Our findings are beneficial to managers in allocating resources to different types of environmental initiative, and provide valuable insight for sustainable environmental investment.

Impact of Ownership Type on Environment–Strategy Linkage and Performance: Evidence from a Transitional Economy

In this study I contend that the ownership type has a significant impact on the environment–strategy configurations amongst different firms in a transitional economy. The influence of ownership type on the environment–strategy configuration is tested, based on an analysis of surveys of 201 managers from four types of companies in China: state‐owned, collectively‐owned, privately‐owned, and foreign joint ventures. Results support the central notion that each ownership type exhibits a distinct environment–strategy configuration, which in turn has important performance implications for the firms.

The Impact of Financial Reporting Regulation on the Market Valuation of Reported Environmental Liabilities: Preliminary Evidence from US and Canadian Public Companies

This study investigates the economic consequences of four financial reporting regulations relating to environmental liability reporting in samples of 170 US and 156 Canadian public companies during the period 1984 to 1997. The study's purpose is to investigate the factors that make financial reporting regulation effective in enhancing the relevance and reliability of accounting information. Prior research provides the theory that financial reporting regulations impose costs on managers and create incentives for them to report accounting information that is relevant and unbiased. This study assesses these regulations' enforceability, which is viewed as arising from the regulator's power to enforce its regulations by sanctions or penalties. It tests whether the relation between market valuation and reported environmental liability accruals changes when the new regulations are enacted, and whether regulation with high enforceability has a more significant impact than regulation with low enforceability. This study uses a residual‐income valuation model to measure the valuation coefficient, or multiplier, on reported environmental liability accruals. Changes in this coefficient are used as indicators of changes in the market's assessment of the value relevance and bias of the reported accounting information. This study provides preliminary evidence indicating that financial reporting regulations issued by the securities market regulator and the accounting profession are associated with changes in the relation between market value and reported environmental liabilities in some cases, and suggests avenues for further international accounting research on the factors involved in financial reporting regulation's impact.     

Wage Differentials and Workers’ Effort: Experimental Evidence from Uganda

We organize a real-effort field experiment with varying piece rates to assess the impact of wages and social comparisons on productivity. In addition to analyzing how piece rates and social comparisons affect productivity during the ‘paid stage’ of the experiment, we also consider how they affect effort supply during a voluntary and unpaid follow-up task. Our main results are that effort supply is relatively unresponsive to variation in own earnings, but responds strongly to pay inequality. While we obtain weak support for the hypothesis that positive social comparisons invite extra effort during paid stages of the experiment, our most important finding is that social comparisons matter for voluntary tasks when shirking is cheap. Specifically, positive social comparisons positively affect productivity during unpaid tasks, and negative comparisons have the opposite impact.
