Women rule: potato markets,cellular phones and access to information in the Bolivian highlands

In highland Bolivia, potato markets are widespread and access to market information has entered the digital age. Information networks lubricated by ubiquitous cellular technologies are supplanting traditional means of information‐gathering. We explore the impacts of access to cellular phones on market selection, use of social networks to acquire information, and gendered responsibilities within the potato market chain near Cochabamba. The entire family participates in potato production and marketing, but responsibilities are differentiated by gender. Men take a leading role in potato production and women in marketing. Access to cellular phones affects decisions about where to market potatoes and improves the potato marketing process.     

Estimation of dynamic panel data models with sample selection

We propose a new method for estimating dynamic panel data models with selection. The method uses backward substitution for the lagged dependent variable, which leads to an estimating equation that requires correcting for contemporaneous selection only. The estimator is valid under relatively weak assumptions about errors and permits avoiding the weak instruments problem associated with differencing. We also propose a simple test for selection bias that is based on the addition of a selection term to the first‐difference equation and subsequent testing for significance of this term. The methods are applied to estimating dynamic earnings equations for women. Copyright © 2011 John Wiley & Sons, Ltd.     

Effects of agency risks and procedural justice on board processes in venture capital-backed firms

This paper builds a model of the effects of agency risk and procedural justice in the boards of directors of venture capital-backed firms. Such boards are unique in that they consist of managers and outside owners with significant power and incentive to be highly involved in venture governance. The authors integrate agency theory and procedural justice perspectives to develop propositions regarding the effects of agency risk and board processes on the responses to poor performance and conflicts of interest. This integrated perspective suggests that factors that increase perceived agency risks will increase outsiders' tendency to focus efforts on monitoring and controlling board decisions and their propensity to resort to formal means to resolve conflicts. However, the authors suggest that through their effects on trust and positive attributions, fair procedures and interactions will reduce these tendencies. A discussion of the practical and theoretical implications of the proposed model concludes the paper.     

The Effects of Competition in Short Product Life‐Cycle Markets: The Case of Motion Pictures*

It is critically important to understand the relationship between new product launch strategies and their interaction with the competitive environment, which results in the successful introduction of new products. Deciding when to launch new products is among the most significant issues facing managers when formulating new products strategy, especially for products with short product life cycles. However, little extant research has focused on the interaction of product launch timing and the competitive market environment. This study explores the effects of four types of competitive threats on the market performance of short product life‐cycle products. Threats from new products and incumbents are possible. Also, products in the same category and those in related product categories exert competitive pressures. In this paper, a framework of competitive threats is developed, and research questions are constructed and empirically tested using the motion pictures industry as the focus of this research. A set of simultaneous equations was estimated using a sample of 2,948 movies introduced in the U.S. market between 1997 and 2004. The results show that all competition types have negative direct, indirect (as mediated by distribution intensity), and total effects on the performance of a new product. For a focal product, incumbent products exert a greater negative impact on performance than new entrants. Surprisingly, products in different, but related, categories are more harmful to the performance of products than products in the same category. The results have important implications for launch timing and new product performance.     

Innovations in Shopper Marketing: Current Insights and Future Research Issues

Shopper marketing refers to the planning and execution of all marketing activities that influence a shopper along, and beyond, the entire path-to-purchase, from the point at which the motivation to shop first emerges through to purchase, consumption, repurchase, and recommendation. The goal of shopper marketing is to enable a win–win–win solution for the shopper–retailer–manufacturer. Shopper marketing has emerged as a key managerial practice among manufacturers and retailers, who are eagerly embracing innovations in the different aspects of shopper marketing. We review current and potential innovations in shopper marketing. We identify the managerial challenges to achieving new win–win–win solutions among shoppers, manufacturers, and retailers in shopper marketing and outline future scenarios and research issues related to these challenges.     

Corporate Equity Ownership, Strategic Alliances, and Product Market Relationships

This paper examines long-term block ownership by corporations and performance changes in firms with corporate block owners. We also examine potential reasons for corporate ownership including benefits in product market relationships, alleviation of financing constraints, and board monitoring by corporate owners. We find the largest significant increases in targets' stock prices, investment, and operating profitability when ownership is combined with alliances, joint ventures, and other product market relationships between purchasing and target firms, especially in industries with high research and development. Our findings are consistent with the conclusion that block ownership by corporations has significant benefits in product market relationships.     

Labor supply responses to marginal Social Security benefits: Evidence from discontinuities

A key question for Social Security reform is whether workers respond to the link on the margin between the Social Security taxes they pay and the Social Security benefits they will receive. We estimate the effects of the marginal Social Security benefits that accrue with additional earnings on three measures of labor supply: retirement age, hours, and labor earnings. We develop a new approach to identifying these incentive effects by exploiting five provisions in the Social Security benefit rules that generate discontinuities in marginal benefits or non-linearities in marginal benefits that converge to discontinuities as uncertainty about the future is resolved. We find that individuals approaching retirement (age 52 and older) respond to the Social Security tax-benefit link on the extensive margin of their labor supply decisions: we estimate that a 10% increase in the net-of-tax share reduces the two-year retirement hazard by a statistically significant 2.0 percentage points from a base rate of 15%. The evidence with regard to labor supply responses on the intensive margin is more mixed: we estimate that the elasticity of hours with respect to the net-of-tax share is 0.42 and statistically significant, but we do not find a statistically significant earnings elasticity. Though we lack statistical power to estimate results within subsamples precisely, the retirement response is driven mostly by the female subsample, while the hours response comes from the male subsample.     

Fund Advisor Compensation in Closed-End Funds

This paper examines the relation between the premium on closed-end funds and organizational features of the funds and advisors, including the compensation scheme of the investment advisor. We find that the fund premium is larger when: (a) the advisor's compensation is more sensitive to fund performance; (b) the assets managed by the advisor are concentrated in the fund in question; (c) the advisor manages other funds with low compensation sensitivity to performance and with low concentration of assets managed by the advisor; and (d) the advisor's compensation contract evaluates performance relative to a benchmark.     

Are Bilateral Remittances Countercyclical?

By putting together a relatively large data set on bilateral remittances of emigrants, this paper is able to shed light on the important hypothesis of smoothing. The smoothing hypothesis is that remittances are countercyclical with respect to income in the worker’s country of origin (the recipient of the remittance), while procyclical with respect to income in the migrant’s host country (the sender of the remittance). The econometric results confirm the hypothesis. This affirmation of smoothing is important for two reasons. First, it suggests that remittances should be placed on the list of criteria for an optimum currency area. Second, it brings into doubt plans by governments in some developing countries to harness remittances for their own use, in that government spending in these countries generally fails the test of countercyclicality which remittances pass.
