Fixed cost,marginal cost,and the decision to buy or make

The paper builds a formal model of the costs and benefits of producing intermediate goods internally as compared to buying partially produced inputs on the open market. The model centers on the link between the purchase of assets specific to a production process and the mean and variance of profits from the purchase. The central point of the paper is that even though purchases of assets specific to a production process can have an ambiguous impact on profits of the decision to make, the purchase of such assets has a tendency to reduce the variability of profits. This trade‐off is at the heart of decision to buy or make. Copyright © 2004 John Wiley & Sons, Ltd.     

Monetary regimes and money supply endogeneity

Quasi-longitudinal Canadian microdata was used to compare the movement of individuals between employers with job changes taking place within firms. Internal mobility is found to be much less common than job changing between firms. Workers changing jobs within a firm are more likely to be older and have higher wages and longer tenures in the jobs they leave than individuals employers. This provides some support for the job-matching hypothesis underlying recent research on the causes of individual mobility, although it is also clear that workers in large or unionized firms are more likely to have the opportunity for internal promotion. While wage gains obtained through internal mobility are smaller than those achieved through external mobility, wage levels are higher for individuals moving within the firm. It is argued that this observation is consistent with a dual labour markets interpretation of mobility patterns.     

Macroeconomic factors, consumer behavior, and bankcard default rates

Over the period from 1981 through 1999, we investigate the relationship between bankcard delinquencies and key macroeconomic variables. Changes in the proportion of accounts in default are statistically related to the consumer debt ratio. When the delinquency rate is calculated based on the number of dollars outstanding, it is related to the total amount of revolving debt. We also find evidence consistent with a pattern of selective default behavior, in which consumers will default on bankcard debt before defaulting on other types of installment loans.

A note on transfer prices and exchange rate pass-through

The paper builds a model of a parent corporation selling an intermediate product to a foreign subsidiary. The model is used to explain the response of foreign prices to changes in the exchange rate between the country of the parent affiliate and the foreign subsidiary. The model examines this response with and without an external market for the intermediate product.     

Market discipline and monetary policy

The effects of forward looking expectations of future inflationon equilibrium inflation and interest rates are examined withinan imperfect information framework. Expectations of future inflationaffect equilibrium in a manner similar to an increase in thecentral bank's weight on future social welfare, making it morelikely an opportunistic central bank will actually deliver onits announced inflation targets, and output expansions can ariseeven if the central banker is revealed to be a low inflationtype. The model also illustrates the channels through whichinflation scares raise current real interest rates.
