Unconventional monetary policy and the dollar–euro exchange rate: first results from time-series analysis

This article examines the impact on the US dollar–euro (USD–EUR) exchange rate of the unconventional monetary policy conducted by the US Federal Reserve (Fed) and the European Central Bank (ECB). To that end, we make use of time-series analysis to obtain a reasonable long-run and short run representation of the data generation process and use dummy variables to study how announcements about monetary policy changes can affect the USD–EUR exchange rate. Our results indicate that the announcement and subsequent implementation of such measures by the ECB would have caused an appreciation of the dollar, while those by the Fed would have caused a depreciation of the dollar.     

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.

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.     

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.     

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.     

Influence of economic crisis on new SME survival: reality or fiction?

The aim of this research was to analyse the survival of new ventures during periods of economic crisis. The article compares survival probability during growth and crisis periods. An empirical study was used to analyse new venture survival probability. Results show that new firms have a greater likelihood of surviving during crisis periods than they do during growth periods. An additional aim of the study was to analyse the survival probability of opportunity and necessity entrepreneurs during crisis periods. Results show that gaps in survival likelihood between opportunity and necessity entrepreneurship are bigger during times of crisis than they are during growth periods.     

Earnings Management in Public Family Firms under Economic Adversity

This paper explores the relationship between the ownership of public firms and their motivation to implement earnings management practices, providing evidence on whether family businesses differ from non‐family businesses in terms of earnings management practices. In addition, it focuses on the possibility of asymmetrical earnings management policies between periods of stability and economic adversity. Based on a sample of Portuguese listed family‐controlled firms for the 1999–2011 period and using a panel data approach, we find no significant differences in the incentive to manage earnings between public family and non‐family firms, suggesting a compensation between the alignment hypothesis, the long‐term orientation of family firms and the desire to pass firms onto succeeding generations, and the entrenchment effect. The evidence shows that earnings management decreases with firms’ profitability, and non‐family firms’ discretionary accruals are mainly influenced by the board of directors. In crisis periods, the discretionary accruals of family firms are especially influenced by firm size. After controlling for different earnings management measures, the determinants of earnings management practices seem somewhat sensitive to the earnings quality proxies. The results provide evidence that directors and policy makers should prevent earnings management procedures in particular situations.
