We quantify the importance of endogenous peer effects in group lending programs by estimating a static game of incomplete information. Endogenous peer effects describe how one's behavior is affected by the behavior of her peers. Using a rich dataset from a group lending program in India, our empirical analysis presents a robust finding of large peer effects. The preferred model suggests that the probability of a member making a full repayment would be 12 percentage points higher if all the fellow members were to make full repayment compared with a scenario in which none of the other members repay in full. We find that peer effects would be overestimated without controlling for unobserved group heterogeneity and that inconsistencies exist in the estimated effects of other variables without modeling peer effects and unobserved heterogeneity.

Behavioral pricing research is cognitively biased. Therefore, the research agenda for this paper is to examine consumers' emotional responses to price information, or price affect. A conceptual framework of price affect based on appraisal theory is proposed. Moreover, a psychometric measure of price affect capturing positive and negative emotions is derived. A field experiment involving N = 1533 consumers reveals that a price increase leads to changes in price affect. Also, negative price affect is related to passive consumer behavior, whereas positive price affect is associated with proactive consumer behavior. Yet, a price increase reduces the importance of price affect in predicting consumer behavior. In addition, both price cognitions and price affect mediate the effect of a price increase on consumer behavior. Consistent with appraisal theory, a price increase exerts its causal influence on price affect through changes in price cognitions. Similarly, price affect mediates the effect of price cognitions on consumer behavior. Finally, price affect improves the prediction of consumer behavior beyond price cognitions. Results suggest that price affect is a stand alone, previously overlooked predictor of consumer behavior. Implications are discussed. © 2008 Wiley Periodicals, Inc. 相似文献

This exercise sets up interlinked labor and goods markets in a classroom macroeconomy. Students with worker roles are endowed with labor that can be consumed or sold to firms that post wages, purchase labor, and produce goods that can be either consumed or sold to workers. The money from sales is used by firms to purchase labor in the next period. Complicated record keeping is avoided by using ordinary playing cards to represent money and goods. The exercise can stimulate a discussion of potential output, unemployment, and the role of money in determining wages and prices. Use: This experiment can be used in introductory macroeconomics classes to teach concepts of the circular flow, real and money wages, unemployment, and labor market equilibrium and in intermediate classes to consider Keynesian and quantity theories. Time required: Fifteen minutes for reading instructions, 30 to 45 minutes for trading (depending on the number of periods), and 15 minutes for discussion. Materials: You will need one copy of the instructions for each person and one deck of ordinary playing cards for each replicated group of two workers and one firm. No money or other incentives are required. 相似文献

In this paper we examine linkages between social trust and economic development using, for the first time, a panel of data. We confirm earlier cross-sectional studies finding that trust is a significant factor in development and also show for the first time that trust significantly interacts with both investment in physical and human capital. We provide a robustness analysis of our results via a set of jackknife experiments on our main equations, and the trust coefficients and interactions are very tightly distributed, indicating that the results are not highly sample dependent. We also consider whether trust directly influences investment and find that in a panel framework it does not unless we allow for a trust–education interaction in the investment equation. 相似文献

The first part of the paper traces the doctrinal origins of the purchasing power parity (PPP) doctrine and reviews the central issues of controversy. The second part is an empirical study covering the flexible exchange rates period of the 1920s. The empirical work examines the efficiency of foreign exchange markets, the absolute and the relative versions of PPP for alternative price indices, the homogeneity postulate, the relation between the short run and the long run, and the patterns of ‘causality’ between prices and exchange rates. The paper concludes with estimations of price equations and a discussion of the proper specification of PPP. 相似文献
