Opening the Black Box: Corporate Codes of Ethics in Their Organizational Context

A review of the literature on Corporate Codes of Ethics suggests that whilst there exists an informative body of literature concerning the prevalence of such codes, their design, implementation and promulgation, it is also evident that there is a relative lack of consideration of their impact upon members' everyday organizational behaviour. By drawing upon organizational sociology and psychology this paper constructs a contextualist and interpretive model which seeks to enable an analysis and evaluation of their effects upon individual, group and organizational behaviour.     

Multilateral and Bilateral Loans versus Grants: Issues and Evidence

This paper examines a wide range of issues relating to the mix between loans and grants as well as the degree of concessionality of loans. A number of empirical tests are carried out based on annual panel data over 1970 to 1999 for 22 donor countries and 72 recipient countries. Based on the tests, we observe that for bilateral donors, past grant‐loan mix (and, hence, reflows from past transfers) do not influence the volume of current resource transfers. Our tests also show that the rate of official borrowing by the recipients (and, by deduction, the extent of their past debt burden) is positively influenced by the extent of the concessionality of such loans – irrespective of whether it is in the form of subsidised interest rates or longer grace periods. The paper concludes with a review of the circumstances in which grants, soft loans and non‐concessional loans might have their respective comparative advantage, as well as a discussion of the need, so as to overcome the negative incentive problems of soft loans, for a typical concessional loan package to be separated into two constituent parts. This would enable the recipient to be given the grant component and the option to take from the non‐concessional loan component as much as desired.     

SUPPLY CHAIN INFORMATION SHARING IN A VENDOR MANAGED INVENTORY PARTNERSHIP

Vendor Managed Inventory (VMI) involves the vendor making the replenishment decision for products supplied to a customer based on various inventory and supply chain policies. Information sharing between supply chain members is required in VMI. Sometimes VMI decisions are delayed and/or the information shared is inaccurate. This research examines the effects of information delay and accuracy, and the sharing of sales and forecast information in a VMI environment facing stationary and nonstationary demand. The simulation experiments show the impact of information delay, information inaccuracy, and information sharing on a variety of performance measures, including inventory levels and fill rates.     

Central bank transparency and market efficiency: An econometric analysis

Blinder (1998) argues that more open public disclosure of central bank policies may enhance the efficiency of markets. We examine this claim by studying whether the Federal Reserve System's 1994 policy shift toward more open disclosure improved or worsened the predictability of financial markets. Employing methods analogous to Campbell and Shiller (1991), we find that since 1994, the forecasting error has decreased for interest rates on U.S. bonds of most maturity lengths, and that the expectations hypothesis has performed better at the low end of the yield curve. These findings are inconsistent with the view that increased central bank transparency will decrease the efficiency of financial markets. The authors would like to thank participants of the 2001 Midwest Macroeconomics Conference and 2001 Missouri Economics Conference for their helpful comments and suggestions. All errors are, of course, the author's.     

Productivity Trends in Europe: Implications for Real Exchange Rates, Real Interest Rates, and Inflation

The paper examines a long–run (neoclassical) framework in which differences in productivity growth across sectors and countries lead to inflation differentials. In a currency union, these inflation differentials imply cross–country differentials in real interest rates. The authors estimate the likely size of these differentials for European Union countries, discuss the potential costs of persistent inflation differentials, and comment on the conflicts they may cause within Economic and Monetary Union (EMU). The analytical framework is a variant of the Balassa–Samuelson "productivity hypotheisis," which relates sectoral productivity trends to trends in the relative price of home goods.     

Temporary controls on capital inflows

During the past decade a number of countries imposed capital controls that had two distinguishing features: they were asymmetric, in that they were designed principally to discourage capital inflows, and they were temporary. This paper studies formally the consequences of these policies, calibrates their potential effectiveness, and assesses their welfare implications in an environment in which the level of capital inflows can be sub-optimal. In addition, motivated by the fact that these types of controls have often been left in place after the dissipation of the shock that lead to the controls being implemented, the paper evaluates the welfare cost of procrastination in removing these types of controls.
