The Role of Learning in Dynamic Portfolio Decisions This paper analyzes the effect of uncertainty about the mean return on the risky asset on the portfolio decisions of an investor who has a long investment horizon. Building on the earlier work of Detemple (1986), Dothan and Feldman (1986), and Gennotte (1986), it is shown that the possibility of future learning about the mean return on the ris...

Supplier evaluation and selection, an important element in supplier-based manufacturing and supply chain management has been gaining attention in both academic literature and industrial practice. In this paper, we presented a modified data envelopment analysis (DEA) method for supplier selection which can operate under conditions of imprecise information. A brief description of the importance o...

In traditional thinking, an arbitrageur will trade immediately once an arbitrage opportunity appears. Is this the best strategy for the arbitrageur or it is even better to wait for the best time to trade so as to achieve the maximum profit? To answer this question, this paper studies the optimal trading strategies of an arbitrageur in a dynamic economy where the arbitrageur’s trades affect pric...

Does power sharing between competing elites result in franchise extension to non-elites? In this paper, we argue that competing, risk-averse elites will enfranchise non-elites as insurance against future, uncertain imbalances in relative bargaining power. We show that negligibly small changes in the bargaining power of non-elites, conditional on enfranchisment, via coalition formation, constrai...

Here we investigate the existence of credit in a cash-in-advance economy where there are complete markets but for the fact that agents cannot commit to repay their debts. Defectors are banned from the credit market but they can use money balances for saving purposes. Without uncertainty, deflation crowds out credit completely. The equilibrium allocation, however, is efficient if the government ...

In this Online Appendix, we conduct additional analysis of the data and robustness checks as well as provide some theoretical analysis. We proceed as follows. At the end of Section 1, we describe the type of statistical analysis we perform to compare treatments and behaviors in different parts of the experiment. This section also contains definitions we use in the Online Appendix. In Section 2,...

This paper estimates a reduced-form model to assess the credit risk of General Insurance (GI) non-life firms in the UK. Compared to earlier studies, it uses a much larger sample including 30 years of data for 515 firms, and also considers a much wider set of possible determinants of credit risk. The empirical results suggest that macroeconomic and firm-specific factors both play important roles...

A new framework, Decerns, for multicriteria decision analysis (MCDA) of a wide range of practical problems on risk management is introduced. Decerns framework contains a library of modules that are the basis for two scalable systems: DecernsMCDA for analysis of multicriteria problems, and DecernsSDSS for multicriteria analysis of spatial options. DecernsMCDA includes well known MCDA methods and...
