On stationary overlapping generations models

Consider a stationary consumption–loan economy with fixed amount of fiat money. We show that although the economy is stationary if the number of goods and the number of ‘types’ of consumers are larger than one, there might be no Pareto optimal stationary competitive equilibrium.     

Mutual savings bank membership in the FHLBS: Motivations behind recent membership growth

Mutual savings bank membership in the Federal Home Loan Bank System increased sharply during 1974–1976. Motivations behind this upsurge in System membership are explored using a financial model of savings bank behavior. Hypotheses regarding the balance sheet structure of banks that joined the System during the period are developed and tested using multiple regression analysis. Empirical results for banks that joined the System in 1975 indicate that the joining banks were aggressive, risk-taking organizations that were attracted to membership in order to have a standby source of ready liquidity. Results for banks joining in other years are weaker, though still generally consistent with the 1975 results.     

Adaptive credit granting policies

We analyze here the optimal interest rate determination of a bank that learns about the repayment behavior of its customers from their past behavior. Optimal dynamic methods are first suggested for determining the interest rate for a bank that learns about the probability of default of its borrowers. It is shown that such a bank determines lower than or equal interest rates than a bank that does not adapt its probability of default according to its past experience. Similar results also obtain when the bank learns about the probabilities that its borrowers belong to each of K (K larger than 2) quality groups.     

Vehicle currency use in international trade

We explore the major driving forces for currency invoicing in international trade with a simple model and a novel dataset covering 24 countries. We contrasts a “coalescing” effect, where exporters minimize the movements of their prices relative to their competitors', with incentives to hedge macroeconomic volatility and transaction costs. The key determinants of invoice currency choice are industry features and country size, with some role for foreign-exchange bid-ask spreads. The coalescing effect also goes a long way to explaining the well-known dominance of the dollar. Trade flows to the United States are predominantly invoiced in dollar, as foreign exporters face competition with U.S. firms. The use of the dollar in trade flows that do not involve the United States reflects trade in homogeneous products where firms need to keep their price in line with their competitors'.     

Aggregation of multiple prior opinions

Experts are asked to provide their advice in a situation of uncertainty. They adopt the decision maker?s utility function, but each has a potentially different set of prior probabilities, and so does the decision maker. The decision maker and the experts maximize the minimal expected utility with respect to their sets of priors. We show that a natural Pareto condition is equivalent to the existence of a set Λ of probability vectors over the experts, interpreted as possible allocations of weights to the experts, such that (i) the decision maker?s set of priors is precisely all the weighted-averages of priors, where an expert?s prior is taken from her set and the weight vector is taken from Λ; (ii) the decision maker?s valuation of an act is the minimal weighted valuation, over all weight vectors in Λ, of the experts? valuations.     

Reputation Building: Small Business Strategies for Successful Venture Development

A positive corporate reputation can be crucial to successful venture development. Making use of the Strategic Reference Point theory, four reputation strategies were conceptualized: 1) dynamic exploitation of existing assets; 2) development of core competencies; 3) image management; and 4) strategic alliances. In a comprehensive investigation of three software enterprises in Israel, companies were found to differ in policies that possibly could lead to a good reputation. One company emphasized the long–term establishment of core competencies and remained a fairly unknown enterprise. A second company accentuated the short–term exploitation of assets and had a middling success in reputation building. A third enterprise invested in a broad spectrum of reputation building strategies and quickly developed a reputation for excellence in the field. In conclusion, corporate success often depends on the extent to which managers develop an integrated package of policies for systematically building the intangible asset of corporate reputation.     

Bargaining In International Trade Under Exchange-Rate Uncertainty

This paper examines the implications of various contracting alternatives between exporting and importing firms on the volume of international transactions. the contracts that we study are determined in a bargaining situation under exchange-rate uncertainty. First we look at contracts which entail an ex ante commitment on price and quantity of exports without the possibility of renegotiation ex post. Second, spot contracts, i.e., the price and the quantity of exports are negotiated after the exchange the rate is known. A third type of contracts consists of ex ante commitment and ex post renegotiation.
