The association between individual audit partners’ risk preferences and the composition of their client portfolios

We explore whether audit partners’ attitude towards risk, as measured by their personal criminal convictions, are reflected in the composition of their client portfolios. Analyzing a unique dataset of Swedish audit partners’ criminal convictions, we find that the clients of audit partners with criminal convictions are characterized by greater financial, governance, and reporting risk than those of audit partners without criminal convictions. Also, clients of audit partners with criminal convictions pay larger audit fees, on average, than those of auditors without criminal convictions.     

National culture and national savings: is there a link?

We study the effect of national culture on economic decisions, focusing on GLOBE cultural dimensions of uncertainty avoidance and future orientation. Specifically, we study the effect of divergence between cultural values and practices (societal aspirations), on the aggregate savings decision. Using the life-cycle model of savings as our basic model, we find that societal aspirations are important in explaining national savings behavior. In particular, we show that societal aspirations relating to future orientation and uncertainty avoidance have a positive effect on the rate of savings. We interpret our findings to indicate that such societal aspirations lead to mistrust in the societal arrangements and institutions, and induce savings as a means of securing the future and reducing uncertainty. To substantiate this interpretation, we utilize the microfinance industry; showing that high societal aspirations are associated with preference for savings through member-owned microfinance institutions (MFIs) over savings through non-member-owned MFIs.     

A dynamic hazard-based system of equations of vehicle ownership with endogenous long-term decision factors incorporating group decision making

The transportation system affects all aspects of our daily lives including relatively long-term decisions on work and home location choice and automobile ownership decisions. The interdependency existing among these three decisions jointly influences household mobility and overall travel patterns. Therefore, a dynamic modeling framework that can account for the effects of interdependencies between vehicle transaction behavior and residential and job location choices is highly desirable. These decisions are made in the household level while individuals’ decisions influence the overall outcome; therefore, it is also important to incorporate a group decision making process within such modeling frameworks.This study introduces a dynamic model for vehicle ownership, residential mobility, and employment relocation timing decisions. These decisions are modeled at the individual level and then sequentially aggregated to the household level if it is required. A hazard-based system of equations is formulated and applied in which work location and residential location changes are included as endogenous variables in the vehicle transaction model while other important factors such as land-use and built environment variables, household dynamics, and individuals’ socio-demographics are also considered.     

On the Effects of Entry in Cournot Markets

In the framework of symmetric Cournot oligopoly, this paper provides two minimal sets of assumptions on the demand and cost functions that imply respectively that, as the number of firms increases, the minimal and maximal equilibria lead to (i) decreasing industry price and increasing or decreasing per-firm output; and (ii) increasing industry price (and decreasing per firm output.) In both cases, per-firm profits are decreasing.
The analysis relies crucially on lattice-theoretic methods and yields general, unambiguous and easily interpretable conclusions of a global nature. As a byproduct of independent interest, new insight into the existence of Cournot equilibrium is developed.     

Cournot Oligopoly and the Theory of Supermodular Games

We reconsider the Cournot oligopoly problem in light of the theory of supermodular games. Invoking the recent ordinal version of this theory proposed by Milgrom and Shannon, we generalize Novshek's existence result, derive the associated uniqueness result, give an extension of a classical existence result under symmetry, and provide conditions making a Cournot oligopoly into a log-supermodular game (with the natural order on the action sets). We also provide extensive and precise insight as to why decreasing best-responses are widely regarded as being “typical” for the Cournot model with production costs. Several illustrative examples are provided.Journal of Economic LiteratureClassification Numbers: C72, L10, L13.     

Economic and sociopolitical determinants of exchange controls

The objective of this study is to explore the feasibility of identifying factors that could presage the imposition of exchange controls. Two sets of variables are argued to contain pertinent information regarding the imposition of controls. One set is composed of 14 economic ratios related to the balance of payments and exchange rate; the other set is made up of 17 proxy measures of sociopolitical instability. The empirical analysis of exchange controls imposed by 13 governments during 1973–1983 shows that these variables have potential for predicting the imposition of exchange controls.     

Psychology, Behavioral Economics, and Public Policy

Economics has typically been the social science of choice to inform public policy and policymakers. In the current paper we contemplate the role behavioral science can play in enlightening policymakers. In particular, we provide some examples of research that has and can be used to inform policy, reflect on the kind of behavioral science that is important for policy, and approaches for convincing policy-makers to listen to behavioral scientists. We suggest that policymakers are unlikely to invest the time translating behavioral research into its policy implications, and researchers interested in influencing public policy must therefore invest substantial effort, and direct that effort differently than in standard research practices.
