The impact of minimum wages on youth employment in Portugal

On January 1, 1987, the legal minimum wage for workers aged 18 and 19 in Portugal was raised by 49.3%. This shock is used as a “natural experiment” to evaluate the impact of the minimum wage change on teenagers’ employment. The method is to compare, based on firm-level microdata, the employment growth of 18-19-year-old workers with employment growth of older workers. The main findings are that the increase in the minimum wage significantly reduced employment of 18 and olds, but increased employment of 20- olds.     

Strategic market games with a finite horizon and incomplete markets

Summary. We study a strategic market game associated to an intertemporal economy with a finite horizon and incomplete markets. We demonstrate that generically, for any finite number of players, every sequentially strictly individually rational and default-free stream of allocations can be approximated by a full subgame-perfect equilibrium. As a consequence, imperfect competition may Pareto-dominate perfect competition when markets are incomplete. Moreover - and this contrasts with the main message conveyed by the market games literature - there exists a large open set of initial endowments for which full subgame-perfect equilibria do not converge to -efficient allocations when the number of players tends to infinity. Finally, strategic speculative bubbles may survive at full subgame-perfect equilibria.Received: 24 January 2002, Revised: 21 February 2003, JEL Classification Numbers: C72, D43, D52.

When a Sinner Does a Good Deed: The Path‐Dependence of Reputation Repair

This study examines how shareholders will interpret a socially desirable action taken by firms with a damaged corporate reputation status. We first explain theoretically why shareholders’ path‐dependent judgments of a tainted firm increase the likelihood of shareholders making less favourable judgments of the firm's socially desirable actions. We then test the theoretical predictions using a sample of Chinese listed firms that were sanctioned for securities fraud and subsequently made donations to the 2008 Sichuan earthquake relief funds. We find that the shareholders evaluate the donations made by fraud‐tainted firms less favourably than those made by firms that have not been sanctioned for fraud. Furthermore, the shareholders’ evaluations of the donations made by fraud‐tainted firms is less favourable if the firms have committed more serious fraud and undertaken fewer positive remedial actions in the post‐fraud period. Overall, our evidence demonstrates that shareholders’ path‐dependent judgments of fraud‐tainted firms constitute a major obstacle that constrains the effectiveness of reputation repair.     

Service climate, professional commitment and job performance of flight attendants in Taiwan

This study of airline managers and flight attendants uses survey information to look at relationships between service climate, professional commitment and job performance. It finds that service climate positively influences professional commitment, influences job performance while professional commitment positively influences job performance and smoothes the relationship between service climate and job performance.     

Analyst Earnings Forecasts for Publicly Traded Insurance Companies

Several trends in the insurance and financial services industry, including demutualizationconsolidation, and deregulation, have attracted increasing attention from investors and financial analysts. This paper investigates the accuracy of the earnings forecasts of financial analysts for insurance companies. Our empirical results indicate that analyst forecasts outperform random walk time-series forecasts. Furthermore, we find that both disagreement over earnings forecasts among analysts and the relative forecasting error in the mean forecasts is smaller for life insurers than for property-casualty insurers, whereas the relative errors for forecasts for multiple-line insurers are in between the two. Forecasting error is a negative function of firm size and the number of analysts who are following a company, and is a positive function of the disagreement among analysts.Analyst forecasts have a timing advantage over the random walk model. Our results also suggest that the fair value reporting requirement (SFAS 115), which has been in effect since 1994, has enhanced the accuracy of analyst forecasts. The SFAS 115 has improved the superiority of analyst forecasts over the random walk forecasts for life insurers, but not for property-casualty insurers, and there is a weak improvement for multiple-line insurers.

The Agency Problems Embedded in Firm’s Equity Investment

We find that agency problems are embedded in firm’s excess and abnormal equity investments that are mainly dictated by controlling shareholder’s motives and ethical choices manifested in ownership and board structure. The excess equity investment is gauged with respect to industry average. The abnormal equity investment is specifically referred to the number of nominal investment companies that are fully controlled by the controlling owners while subject to little governance. Our empirical evidences of 345 Taiwanese non-financial listed firms show that firm’s excess and abnormal equity investments are negatively correlated with controlling shareholder’s cash flow rights while are positively correlated with the control–cash flow deviation, and board affiliation. The results are supportive of the positive incentive hypothesis and the negative entrenchment hypothesis put forth by La Porta et al. (2002, Journal of Finance 57, 1147–1171) and Claessen et al. (2002, Journal of Finance 57, 2741–2742). The negative relation between equity investment and firm’s value further supports the agency postulation that corporate excess and abnormal equity investments represent a leeway for controlling shareholder to exploit wealth of minority shareholders. This study potentially contributes to the literature of business ethics by portraying an empirically testable linkage from controlling owner’s ethical choices to his actions and therefore firm’s value.

Uncovering Micro‐Practices and Pathways of Engagement That Scale Up Social‐Driven Collaborations: A Practice View of Power

This paper explores how large‐scale social‐driven collaborations might grow in scale and help promote political change. We present the results of a qualitative investigation of a complex platform where multiple and hybrid collaborations co‐exist and where civil society plays a central role. Based on a longitudinal comparative case study, we draw a processual model describing micro‐practices and pathways of engagement. We show that the emergence of these collaborations requires a new type of convener, one that is able to manage the interplay between the sharing/co‐creation of abundant resources and the coordinated decentralization of informal authority. Our study extends existing debates on the role of resources and authority, showing the complementarity between possession and practice perspectives of power. Finally, we identified synergies between collaboration and social movement literatures, particularly showing that large‐scale collaborations could be mobilized to refine social movement agendas and achieve more purposive collective action.
