Developing a decision rule to predict failure: The case of savings and loan associations

The relative costs of misclassifying institutions by their financial health is an issue that concerns researchers. In this paper, a model and decision rule are developed that improve the probability of identifying those Savings and Loans that are predicted not to fail, but are actually failing. For obvious reasons, stakeholders in those institutions are very much interested in avoiding this type I error. The study also makes available evidence that the examination of Z-scores can be useful in identifying other financial institutions that may experience financial failure.     

An Examination and Validation of Linguistic Constructs for Studying High-Stakes Deception

Theories of deception have produced upwards of 150 potential verbal and nonverbal communication indicators. Of these, approximately 30 indicators, or cues, have been used previously with automated linguistic analysis tools to study text-based communication. The current research examines the interrelationships among these cues and proposes a set of specific constructs to be validated for high-stakes deception research. We analyzed linguistic-based cues extracted from 367 written statements prepared by suspects and victims of crimes on military bases. Confirmatory factor analysis was used to evaluate two models. The superior model retained seven constructs: quantity, specificity, affect, diversity, uncertainty, nonimmediacy, and activation.     

A time‐series analysis of Zimbabwe's corn sales to the Grain Marketing Board

This article considers methods of cointegration testing to construct a model of Zimbabwe ‘s corn sector. Corn production, sales of corn to the government, the price of corn, and price of beef are linked together in one long‐run equilibrium (cointegrating) relation. Only the price of beef is not weakly exogenous to perturbations in this relation. That is to say, when these variables are out of long‐run equilibrium, it is through subsequent changes in the price of beef that equilibrium is restored. The other variables do not respond to a long‐run disequilibrium. Short‐run forecasts from this model are compared with expert opinion forecasts made by the government's marketing board. Possibilities for improvement in long‐run forecasting and planning are discussed.     

Labor force participation and pair-wise efficient contracts with search and bargaining

A “constant” wage is pair-wise inefficient in a standard search model when workers endogenously separate from employment. We derive a pair-wise efficient employment contract that involves workers paying a hiring fee (or bond) upon the formation of a match. We estimate the constant wage and pair-wise efficient contract assuming the hiring fee is unobservable, and find evidence to reject the pair-wise efficient contract in favor of the constant wage rule. A counterfactual experiment reveals the current level of labor force participation to be 9.6% below the efficient level, and a structural shift to the pair-wise efficient contract improves welfare by roughly 3.5%.     

Is Beta Dead or Alive?

The debate about whether beta is dead or alive has heated up once again. We believe the empirical work supporting either side of the argument is limited because market frictions are not adequately addressed. This study clarifies the controversy about the issue by creating a new moving-average beta and analyzing two market anomalies: the turn-of-the-year and the Monday effects. What is discovered in this research is (1) that a fundamental source of the problem underlying the two types of market anomalies is the persistence of market frictions that retard the arbitrage process; (2) that beta is seriously ill if the effects of market frictions are ignored; and (3) that beta is alive and well if the effects of market frictions are accommodated. Also, we show, by using an optimal lead/lag structure, the moving-average beta provides significantly higher explanatory power for the turn-of the-year and the Monday effects than betas created from ordinary least squares regression and Scholes-Williams and Fama-French methods because the moving-average beta accommodates the effects of market frictions into the body of beta itself. This new type of beta, a moving-average beta, is demonstrated to be robust.     

China's Accession to the World Trade Organization: What Is at Stake for Agricultural Markets?

We analyze the impact of China's accession to the World Trade Organization on major crop and livestock markets using the Food and Agricultural Policy Research Institute (FAPRI) modeling framework. We incorporate expected changes in consumer income, textile production, and trade policies as exogenous shocks to the baseline model. Following accession, revenues decline in China's livestock, grain, and oilseed industries, while cotton production prospers despite increased imports. Chinese consumers benefit from lower food prices, with vegetable oil, dairy, and meat consumption increasing significantly. Argentina, Brazil, Canada, the European Union, and the United States are the greatest beneficiaries from expanded agricultural trade with China.
