THE COST STRUCTURE OF MICROFINANCE INSTITUTIONS IN EASTERN EUROPE AND CENTRAL ASIA

Microfinance institutions are important, particularly in developing countries, because they expand the frontier of financial intermediation by providing loans to those traditionally excluded from formal financial markets. This paper presents the first systematic statistical examination of the performance of MFIs operating in Eastern Europe and Central Asia. A cost function is estimated for MFIs in the region from 1999-2004. First, the presence of subsidies is found to be associated with higher MFI costs. When output is measured as the number of loans made, we find that MFIs become more efficient over time and that MFIs involved in the provision of group loans and loans to women have lower costs. However, when output is measured as volume of loans rather than their number, this last finding is reversed. This may be due to the fact that such loans are smaller in size; thus for a given volume more loans must be made.Eastern Europe, banking, microfinance, efficiency

Testing for Hypothetical Bias in Contingent Valuation Using a Latent Choice Multinomial Logit Model

The most persistently troubling empirical result in the contingent valuation method literature is the tendency for hypothetical willingness to pay to overestimate real willingness to pay. We suggest a new approach to test and correct for hypothetical bias using a latent choice multinomial logit (LCMNL) model. To develop this model, we extend Dempster, Laird, and Rubin’s (1977) work on the EM algorithm to the estimation of a multinomial logit model with missing information on categorical membership. Using data on both the quality of water in the Catawba River in North Carolina and the preservation of Saginaw wetlands in Michigan, we find two types of “yes” responders in both data sets. We suggest that one set of yes responses are yea-sayers who suffer from hypothetical bias and answer yes to the hypothetical question but would not pay the bid amount if it were real. The second group does not suffer from hypothetical bias and would pay the bid amount if it were real.C25, P230, Q51

Specification Search and Levels of Significance in Econometric Models

This paper describes the problem specification searches pose for inference, presents the results of some simulations for purposes of illustration, and uses the bootstrapping procedure to give a better estimate of statistical significance than a standard t-test. The value of the illustrations of specification searches is that they help demonstrate the severity of the problem. The examples presented here illustrate that in most cases, a researcher can undertake specification search and report a statistically significant result regardless of whether the variables in a regression equation are actually related. The bootstrap procedure used to analyze the specification searches does provide another way to examine the true statistical significance of empirical results. Two different specification searches are examined: a "drop insignificant coefficients" search and a "biggest t-ratio" search. Both are shown to lead to larger than reported standard errors. In general, standard errors get larger if a specification search has taken place, but exactly how much larger must be determined on a case-by-case basis.

Estimation of a selectivity model with misclassified selection

Despite the great interest in models of self-selection and models with misclassification, there have been few studies combining the two. Notable exceptions are given by McCarthy, Millimet, and Roy and Shiu. None of these models have been developed in a contingent valuation setting that we are interested in. The goal of this note is to add to this literature by presenting a model for estimating willingness to pay using data collected through a contingent valuation survey. We examine the case of a selectivity model in which the outcome equation is interval censored but the decision indicator is not observed

Television Revenue and the Structure of Athletic Contests: The Case of the National Basketball Association

This study points out that changes in the format of the playoffs in the National Basketball Association have had the effect of lengthening the championship series and reducing the variance in the length of the series. These are valuable goals for the organization because they provide higher television ratings and revenues for the teams involved. Empirical evidence presented here suggests that viewership among 1.2 million additional households is at stake.Basketball; Television

Professor Gopal Kanji\u27s Retirement as Editor of Journal of Applied Statistics

(First paragraph) This. issue of Journal of Applied Statistics marks the first in its history which does not fall under the editorship of its founder Professor Gopal Kanji. Following his retirement from the role we would like to use this editorial to outline the history and development of the Journal and pay tribute to the many achievements of Gopal’s career

“Yet” ~ A Brief School-Based Program for Fourth Graders

“Yet” is a school-based youth development program intended to introduce elementarygrade students to concepts of growth mindset, self-leadership, resilience and self-talk to promote healthy coping strategies to persist in tasks toward more positive educational outcomes.  Drawing from psychology, education, and management literature focusing on self-leadership, the “Yet” program encourages interaction and internalization of concepts such as “growing the brain,” and “stinkin’ thinking,” while modeling how to reframe set-backs to things students have not mastered…”yet,” and practicing adaptive self-talk to promote coping and persistence.  This unique program holds promise because it is approximately 30 minutes long, occurs within the context of a regular school day, and can be implemented with a high measure of fidelity because it is script-based.  The success of the program may be augmented by principal and teacher support along with online videos

Inside Post-Socialist Courts: The Determinants of Adjudicatory Outcomes in Slovenian Commercial Disputes

Despite the judiciary's central role in the capitalist market system, micro-level empirical analyses of courts in post-socialist countries are remarkably rare. This paper draws on a unique hand-collected dataset of commercial claims filed at Slovenian courts to examine the determinants of two salient adjudicatory outcomes: whether a case was resolved via trial or settlement and if the case was tried, whether the plaintiff was awarded the initial claim. Consistent with the divergent expectations theory of litigation, we find that trial-based resolution is more likely when the case is complex and less likely when parties use mediation. Addressing sample selection and endogeneity concerns, we show that defendant's legal representation, plaintiff's profitability, and, importantly, court identity are robust predictors of plaintiff victory at trial. Thus, more than two decades after the start of transition in Slovenia, the judicial system is still a source of legal inconsistency and uncertainty
