Negative nominal interest rates: Three ways to overcome the zero lower bound

The paper considers three methods for eliminating the zero lower bound on nominal interest rates and thus for restoring symmetry to the domain over which the Central Bank can vary its official policy rate. They are: (1) abolishing currency (which would also be a useful crime-fighting measure); (2) paying negative interest on currency by taxing currency; and (3) decoupling the numéraire from the currency/medium of exchange/means of payment and introducing an exchange rate between the numéraire and the currency; this exchange rate can be set over time to achieve a forward discount (expected depreciation) of the currency vis-à-vis the numéraire when the nominal interest rate in terms of the numéraire is set at a negative level for monetary policy purposes.     

Credit constraints and smallholder dairy production in the East African highlands: application of a switching regression model

Accurate assessment of farmers' credit constraint condition is important in order to understand the circumstances under which credit would have its greatest impact. In this study a switching regression model was used to determine the impact of credit on smallholder dairy farms in the East African highlands using farm level data from Ethiopia and Kenya. Farmers were classified as credit constrained or credit non-constrained based on their responses from the farm level surveys. No consistent relationship was found between farmers' credit constraint condition and their borrowing status. Most of the variation in milk output per farm was explained by the number of crossbred milking cows in the dairy herd. As credit is likely to facilitate investment in crossbred dairy cows it will have substantial impacts on smallholder dairy farms especially if it is targeted to credit constrained farms.     

A Meta-Analysis of Achievement Motivation Differences between Entrepreneurs and Managers*

As a result of conflicting conclusions in primary studies, most narrative reviews have questioned the role of personality in explaining entrepreneurial behavior. We examine one stream of this research by conducting a meta-analysis of studies that contrast the achievement motivation of entrepreneurs and managers. The results indicate that entrepreneurs exhibit higher achievement motivation than managers and that these differences are influenced by the entrepreneur's venture goals, by the use of U.S. or foreign samples, and, to a less clear extent, by projective or objective instrumentation. Moreover, when the analysis is restricted to venture founders, the difference between entrepreneurs and managers on achievement motivation is substantially larger and the credibility intervals do not include zero.     

Valuing ARM Rate Caps: Implications of 1970–84 Interest Rate Behavior

This paper computes how coupon rates on hypothetical default-free 1- 3- and 5-year adjustable rate mortgages with various caps and teaser rates issued during the 1970–76 period would have had to be set in order for the ARMs to have earned the market rate of return over a 7 1/2-year holding period. The 1970–84 period includes both a relatively stable interest rate experience (1970–77) and a "worse case" sharply rising rate environment (1977–84). Thus the calculations include the entire gamut of margins that lenders might need to charge for various caps in order to earn the market rate of return. What margins lenders should be charging at any point in time depends on the relative likelihood of future interest rate paths, e.g., the 1970–77 pattern versus the 1977–84 pattern. More formally, the appropriate charge depends on the slope of the yield curve and the perceived volatility of interest rates.
