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.

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.     

Marketplace and personal space: Investigating the differential effects of attachment style across relationship contexts

An individual's tendencies in purely personal relationships seem to lead to related tendencies in consumer relationships. The following article presents a study that illustrates how individual differences in personal relationship attachment style can be used to predict the likely success of consumer relationships. In addition, it illustrates how the success of consumption versus nonconsumption relationships can be explained by the effect of attachment style on the individual's perception of qualities of the relationship. © 2006 Wiley Periodicals, Inc.     

Does Advertising Overcome Brand Loyalty? Evidence from the Breakfast‐Cereals Market

In differentiated product markets where consumer preferences are characterized by brand loyalty, an important role for advertising may be to overcome brand loyalty by encouraging consumers to switch to less familiar brands. Using a scanner panel dataset of breakfast-cereal purchases, I find evidence consistent with the hypothesis that advertising counteracts the tendencies of brand loyalty toward repeat purchasing. Equivalently, advertising reduces switching costs in this market. Furthermore, counterfactual experiments demonstrate that in markets with brand loyalty, advertising is an attractive and effective option—relative to alternative promotional activities, such as price discounts—of stimulating demand for a brand .     

Medical insurance with rank-dependent utility

Summary. A well-known result in the medical insurance literature is that zero co-insurance is never second-best for insurance contracts subject to moral hazard. We replace the usual expected utility assumption with a version of the rank-dependent utility (RDU) model that has greater experimental support. When consumers exhibit such preferences, we show that zero co-insurance may in fact be optimal, especially for low-risk consumers. Indeed, it is even possible that the first-best and second-best contracts are identical. In this case, there is no “market failure”, despite the informational asymmetry. We argue that these RDU results are in better accord with the empirical evidence from US health insurance markets.

Network externalities and long-run market shares

We study a dynamic duopoly model with network externalities. The value of the product depends on the current and past network size. We compare the market outcome to a planner. With equal quality products, the market outcome may result in too little standardization (i.e. too many products active in the long run) but never too much. The potential inefficiency is non-monotonic in the strength of the network effect, being most likely for intermediate levels. When products differ in quality, an inferior product may dominate even when the planner would choose otherwise, but only if the discount factor is sufficiently large     

The outsourcing of R&D through acquisitions in the pharmaceutical industry

We examine the performance of 160 pharmaceutical acquisitions from 1994 to 2001 and find evidence that on average acquirers realize significant positive returns. These returns are positively correlated with prior acquirer access to information about the research and development activities at target firms and a superior negotiating position. A unique Desperation Index is employed to determine the current status of a firm's internal productivity. We find that firms experiencing declines in internal productivity or which are more desperate are more likely to engage in an outsourcing-type acquisition in an effort to replenish their research pipelines.     

Anxiety of dependency in international joint ventures? An empirical study of drivers and consequences of relationship insecurity

This research introduces and delineates the concept of insecurity in IJV relationships. We define relationship insecurity as a parent firm's concerns about the continuance of the alliance arrangement and its partner's future provision of need satisfaction. According to interdependence theory, exchange partners that experience high dependence inevitably experience this ‘anxiety of dependency’, and the emergence of insecurity can destabilize the working relationship from within. We develop a conceptual model of the drivers and consequences of relationship insecurity in IJVs. Our survey results from 125 IJVs indicate that focal firm dependence and partner firm dependence both negatively affect insecurity, though the former is the dominant predictor. This surprising finding implies IJV partners experience ‘anxiety of low dependency’. The results suggest insecurity not only reduces directly IJV performance, but also lowers the quality of interpartner communication, which in turn dampens performance. Implications of these results are discussed.
