THE DURATION OF FIRM-DESTINATION EXPORT RELATIONSHIPS: EVIDENCE FROM SPAIN, 1997-2006

2012

I. INTRODUCTION The traditional trade literature that investigates aggregate trade flows emphasizes the sizeable increase in trade relationships since World War II and the remarkable persistence of trade flows. However, recent microlevel studies point out that under the stable aggregate trade flows there is a rich dynamics at firm- and/or product-level with a high turnover. In fact, international-market presence is often a transitory and an uncommon phenomenon. At any period, only a small percentage of home-based firms participate in trade and exporting firms are different from non-exporters (larger, more productive, etc.). Moreover, there is much persistence in exporting status; being an e…

Political risk and export promotion: evidence from Germany

2008

Political risk represents an important hidden transaction cost that reduces international trade. This paper investigates the claim that German public export credit guarantees (Hermes guarantees) mitigate this friction to trade flows and hence promote exports. We employ an empirical trade gravity model, where we explicitly control for political risk in the importing country in order to evaluate the effect of export guarantees. The idea behind export promotion through public export credit agencies (ECAs) is that the private market is unable to provide adequate insurance for all risks associated with exports. As a consequence, firms' export activities are limited in the absence of insurance pr…

Is the long-run underperformance of seasoned equity issues irrational? Evidence from Spain

2007

Abstract We investigate if the long-run underperformance in the year after the issue of a sample of Spanish SEO firms is related to behavioural biases that lead investors to slowly adjust their pre-issue overoptimism. We also examine the existence of arbitrage costs that preclude mispricing from being corrected rapidly by sophisticated investors who act as arbitrageurs. Our findings support the contention that small SEO firms are overpriced at the time of the issue and suggest that their post-underperformance is related to arbitrage costs, where transaction costs play an important role although holding costs do not.

Governance forms drivers in bio-pharmaceutial inter-firm relationships

2012

Networking benefits are acknowledged by many studies in the industrial organization and strategic management fields; transaction cost theory agency and property right theory provide the economic foundations to the market-hierarchy dilemma; while Resource based-view (RBV), relational and evolutionary theories provide the strategic foundation of the inter-firm relationships. All this theoretical strands investigate reasons that push firms to formalize their relationship in different governance structures. The bio-pharmaceutical industry has the characteristics to offer to the potential partners both exploitation or exploration alliances benefits. In particular some elements play a “pivot” rol…

Optimal Index Tracking Under Transaction Costs and Impulse Control

1998

We apply impulse control techniques to a cash management problem within a mean-variance framework. We consider the strategy of an investor who is trying to minimise both fixed and proportional transaction costs, whilst minimising the tracking error with respect to an index portfolio. The cash weight is constantly fluctuating due to the stochastic inflow and outflow of dividends and liabilities. We show the existence of an optimal strategy and compute it numerically.

Efficient analytic approximation of the optimal hedging strategy for a European call option with transaction costs

2006

One of the most successful approaches to option hedging with transaction costs is the utility-based approach, pioneered by Hodges and Neuberger [Rev. Futures Markets, 1989, 8, 222–239]. Judging against the best possible trade-off between the risk and the costs of a hedging strategy, this approach seems to achieve excellent empirical performance. However, this approach has one major drawback that prevents the broad application of this approach in practice: the lack of a closed-form solution. We overcome this drawback by presenting a simple yet efficient analytic approximation of the solution. We provide an empirical testing of our approximation strategy against the asymptotic and some other …

THE IMPACT OF ELECTION RESULTS ON THE MEMBER NUMBERS OF THE LARGE PARTIES IN BAVARIA AND GERMANY

2005

In this paper, we investigate the relations between the numbers of members of various parties and their results in the elections in Bavaria and in Germany. Deriving from the finding that there is a strong time-delayed correlation between these data-sets for the two largest parties in Bavaria, we show in a simulation based on the Sznajd model that such a correlation leads to very stable majorities, just as in Bavaria.

Trend Following with Momentum Versus Moving Average: A Tale of Differences

2018

Despite the ever-growing interest in trend following and a series of publications in academic journals, there is still a great shortage of theoretical results on the properties of trend following rules. Our paper fills this gap by comparing and contrasting the two most popular trend following rules, the Momentum (MOM) and Moving Average (MA) rules, from a theoretical perspective. Our approach is based on the return-based formulation of trading rules and modelling the price trends by an autoregressive return process. We provide theoretical results on the similarity between various trend following rules and the forecast accuracy of trading rules. Our results show that the similarity between t…

The role of the economic crisis on the competitiveness of the agri-food sector in the main Mediterranean countries

2014

Th e world economic crisis that, since 2008 has also struck the real economy, cannot be attributed only to the United States bubble which in 2007 involved the mortgage credit market, but it is the result of a series of factors among which the imbalance of the fi nancial market, of the public accounts of the main economies and the real sector. Also agricul- ture, which has always been considered an anti-cyclic sector, has seen a strong slowdown with a plunge in the trade fl ows. Th is paper analyses the changes which happened to the competitive position in the world market of some Mediterranean countries and of France, Italy, Spain and Turkey in particular trying, moreover, to understand the…
