Implicit exchange regimes in Central and Eastern Europe: a first exploration

This paper attempts to identify implicit exchange rate regimes for currencies of the Central and Eastern European Countries vis-à-vis the euro. To that end, we apply a sequential procedure that considers the dynamics of exchange rates to data covering the period from 1977:01 to 2006:02. Our results would suggest that implicit bands have existed in many subperiods for almost all currencies under study. Once we detect de facto discrepancies between de facto and de iure exchange rate regimes, we propose a model in order to explain these decisions. Our results suggest a positive association between the previous inflation rate and the probability of a peg with the euro, and a negative association with past unemployment rate.

Licensing as an Alternative to Foreign Direct Investment

This article addresses issues linked to the sales of manufacturing technology and know-how through licensing by British companies to unaffilated firms located overseas. It identifies a number of characteristics that make these companies more likely to license abroad. The authors test a model of foreign licensing on data gathered from 145 firms based in the United Kingdom. Many companies do evaluate licensing to unaffilated firms as an alternative to foreign direct investment when they consider manufacturing in foreign markets. These firms tend to be relatively large in their industry, highly diversified, spend a relatively higher proportion of their value-added on research and development, and have less foreign experience.     

The interaction of the financing and investment decisions: Preliminary results in the Australian context

This paper investigates the presence of the interaction of investment and financing decisions in Australian firms. Using simultaneous equations incorporating the variables of investment, dividend, and new debt issue, interactive effects are found for two sub-periods.     

Burgernomics: the economics of the Big Mac standard

In the course of PPP research, much of the debate over the validity has been over the choice of an appropriate ‘basket’ for making purchasing power comparisons. The different compositions of goods and services in these baskets across countries have resulted in arguments against their usefulness for PPP purposes. This problem is augmented by the existence of productivity differentials in traded and non-traded goods across countries. Therefore we consider the use of the Big Mac as the international monetary standard as being a more palatable alternative: It is produced locally in over 80 countries around the world, with only minor changes in recipe and thus has the flavour of ‘the perfect universal commodity’. Our results indicate that the Big Mac Index is surprisingly accurate in tracking exchange rates over the long-term, which is consistent with previous PPP research findings. We subsequently enhance our PPP comparisons by taking into account the productivity differentials between countries and excluding non-traded goods from the Big Mac Index to derive the No-Frills Index.     

SYSTEMATIC RISK IN A PURELY RANDOM MARKET MODEL: SOME EMPIRICAL EVIDENCE FOR INDIVIDUAL PUBLIC UTILITIES

A minimum norm quadratic (MINQU-) type of OLS estimator is derived. The estimator is used to test if the betas of the single factor market (SFM) model are random for a sample of utilities for two contiguous periods. The estimated betas for individual utilities vary considerably over time. The statistical significance of such nonstationarity depends on both the utilities and period studied. The relative reduction in the mean square error (MSE) from using a GLS (and not OLS) estimator of beta, when beta is purely random, can be substantial for some utilities but is modest on average.     

Price as a quality signal in a strategic competition context: The role of a disclosure law

This paper analyses a firm's incentive to use price as a signal of quality in a duopoly competition, even though she can credibly and costlessly disclose her true quality. When a firm sets a higher price to signal higher quality, it has strategic effects on the price chosen by her rival. This could result in higher equilibrium prices and profits. Hence, a mandatory disclosure law is useful to prevent the practice of using of higher price as a device to signal higher quality, and in turn equilibrium prices would be lower. From a welfarist point of view, this argument justifies the establishment of such disclosure law.JEL Classification: D43, D82, K29I would like to thank Dolors Berga, Nicolas Boccard, Ramon Caminal, Carmen Matutes, José Luis Moraga and Ricard Torres for their useful comments.

Did the AFL equalization policy achieve the evenness of the league?

In this article, we investigate whether the Australian Football League intervention policies coincided with a more even-playing field in the league, as captured by individual match margins. We find that only two out of the eight major policies implemented over the last hundred years are correlated with lower margin.     

The US National Tobacco Settlement: the effects of advertising and price changes on cigarette consumption

This paper provides an econometric analysis of the effects of cigarette price and advertising changes stemming from the United States Tobacco Settlement of 1998. This is done by estimation of a demand function for cigarettes, based on data from both before and after the Settlement. The model is estimated using monthly time series data for the period 1990–2000. Results show that the increase in cigarette prices stemming from the Settlement reduced per capita cigarette consumption in the USA by 8.3%. However, the cigarette companies also increased advertising in the years immediately preceding and following the Settlement. This study estimates that this increased advertising partially offsets the effects of the higher prices, increasing cigarette consumption by 2.7 to 4.7%, and hence blunting the effects of the price increase by 33–57%.     

Relative Robust Portfolio Optimization with benchmark regret

We extend Relative Robust Portfolio Optimization models to allow portfolios to optimize their performance when considered relative to a set of benchmarks. We do this in a minimum volatility setting, where we model regret directly as the maximum difference between our volatility and that of a given benchmark. Portfolio managers are also given the option of computing regret as a proportion of the benchmark’s performance, which is more in line with market practice than other approaches suggested in the literature. Furthermore, we propose using regret as an extra constraint rather than as a brand new objective function, so practitioners can maintain their current framework. We also look into how such a triple optimization problem can be solved or at least approximated for a general class of objective functions and uncertainty and benchmark sets. Finally, we illustrate the benefits of this approach by examining its performance against other common methods in the literature in several equity markets.
