Price Linkages Between the US,Japan and UK Stock Markets

This study presents an empirical analysis of the short- and long-term relationships among stock prices in the US, Japan and the UK. We re-examine the evidence of market linkages and cointegration between S&P 500, Nikkei 225 and FTSE-100 stock indices. The results suggest that mature markets are cointegrated, indicating a stationary long-run relationship. Furthermore, Granger causality tests show a bi-directional causality between Nikkei 225–FTSE-100, and unidirectional causalities between S&P 500–FTSE-100 and S&P 500–Nikkei 225. These findings suggest that the potential for diversifying risk by investing in mature markets is limited.     

A partial adjustment model with rational expectations applied to the goat sector in Greece

In this paper an attempt is made to examine the rational expectations hypothesis for the goat-meat sector in Greece within the framework of a single equation method that describes the factors affecting demand and supply. The structural equations of the model are estimated by applying the Cochrane-Orcutt technique. The calculated elasticities suggest that Greek goat producers should pay more attention to milk rather than meat production. Statistical indications also confirm the effects of the Chernobyl accident upon the goat sector. Moreover, the forecasting ability of the model has been tested using simulation procedures, which indicate a small deviation between theoretical and observed values. Finally, some further implications concerning the goat sector are drawn from this analysis.     

Innovation diffusion models expressing asymmetry and/or positively or negatively influencing forces

Two different characteristics of the innovation diffusion process, that is, the asymmetry and the appearance of positively or negatively influencing forces, are analyzed. Related diffusion models in use are presented and new generalized models are formulated. A five-parameter model is proposed in order to cover the above two different characteristics of innovation diffusion. The properties of this model and other related diffusion models are examined and the appropriate iterative nonlinear regression analysis technique is developed. Five comparative applications follow, predictions are made, as are comparisons between two generalized models—GRM₁ and Von Bertalanffy—that express asymmetric diffusion behavior.     

Money, Income and Inflation in Equilibrium – The Case of Greece

The specification of the linear long-run relationship among money, income and the opportunity cost of holding money has been a popular study in economic literature. In the specific case of Greece, numerous articles investigated this relationship using quarterly data, mainly of the period after 1960. The objective of this article is to investigate the same long-run relationship using annual data and covering the historical period between 1858 and 1938. The results of the used cointegration analysis are presented along with the findings of other authors who covered the post war era of the Greek Economy.

The Feldstein–Horioka puzzle across EU members: Evidence from the ARDL bounds approach and panel data

This paper addresses the saving-investment (SI) correlation for the EU15 member countries, using the ARDL approach and panel regressions. If we accept the Feldstein–Horioka [Feldstein, M. and C. Horioka, 1980, Domestic saving and international capital flows, Economic Journal 90, 314–329.] interpretation of the SI correlation, the evidence from the ARDL approach does not point to any particular direction in terms of country size, or level of development, or economic and capital market structure. Panel regressions yield an SI coefficient in the range of 0.148–0.157. This finding is attributed to higher capital mobility, lower transaction costs in the international capital markets, and the declining status of long-run current account targeting as a primary government objective.     

Do Family Owners Use Firm Hedging Policy to Hedge Personal Undiversified Wealth Risk?

We examine whether family ownership affects the value impact of the operational and financial dimensions of firms’ hedging policies. We show that family firms’ market valuations are higher than those of non‐family firms, consistent with the view that family firms benefit from family owners’ long‐term perspectives and ability to monitor managers. In addition, while both operational and financial hedging policies per se are valuable in non‐family firms, they do not create any value in family firms. These results support the notion that the founding families’ need to hedge the risk of their undiversified personal wealth portfolio leads to suboptimal risk management decisions.     

Export experience counts: exploring its effect on product design change

In this paper, we explore how managers' export experience can affect the change in product design following changes in perceived past performance. Using data from 519 Portuguese exporters, we find that performance improvement will encourage safe decision making in which firms either will not change the product design or will change it in a way that makes it more similar across the product range. However, when managers' export experience is greater, they encourage change in ways that could support product differentiation. The abilities of experienced managers to read the market, i.e. to interpret changes in performance and translate them into product specifications, help explain these findings. We contribute to the literature in two ways. First, we explore the relationship among past export performance change, product design, and managers' export experience. Second, we identify specific kinds of design changes that firms adopt in response to changes in different dimensions of organizational performance. Based on our findings, we would recommend to new product development managers to consider both managers' export experience and the dimension used to measure performance when evaluating calls for standardizing the design by export managers. Our findings suggest that such calls could be driven by short‐term gains in export performance. Furthermore, we would also emphasize the need to routinely capture information from experienced export managers to ensure that it is considered in future decisions about design changes.     

Derivatives Use, Information Asymmetry, and MNC Post-Acquisition Performance

We utilize a sample of US acquiring firms that engaged in international M&As to document the effects of corporate derivatives use on post-M&A long-term performance. We find that derivatives users outperform nonusers. Furthermore, we find that acquirers with derivative policies that are more comprehensive and sophisticated outperform those with less comprehensive and sophisticated policies. They, in turn, outperform acquirers with no existing policies in place. Our results are consistent with the notion that the use of derivatives lowers information asymmetry related agency problems. Furthermore, our evidence indicates that derivatives use is an important corporate activity that has a profound effect on post-M&A performance.
