Corruption and International Trade: An Empirical Investigation of African Countries

This paper attempts to estimate the effect of corruption on the flows of exports and imports of African countries. Using the gravity model approach and annual data for the period 1998–2007, we obtain negative and statistically significant correlations between the values of exports and imports and the levels of corruption in Africa and trading partners. Thus the results support the view that corruption adversely affects international trade. Our estimates suggest that if a country with Africa’s average corruption perception index of 2.8 were to improve its corruption level to Botswana’s 5.9, its exports would improve by about 15 per cent and imports by about 27 per cent.     

THE EFFECT OF OWNERSHIP IN NGOS’ COMMERCIAL VENTURES

ABSTRACT: Amidst pressure to become self‐financing, Non‐Governmental Organizations (NGOs) have become increasingly involved in profit‐generating business ventures. Because NGOs are traditionally financed by donations with the expectation that they focus on their social mission, the commercialization of NGOs has generated criticism. This paper examines the effect of ownership on investment incentives in NGOs’ commercial ventures, using an incomplete contracts framework. NGO‐ownership helps minimize the tension between primary social mission and managerial decisions. However, external ownership provides better incentives to invest in mission‐enhancing innovations. Finally, because relationships with firms are repeated, NGOs may use relational contracts to align their ventures’ incentives. However, such contracts need to be credible to work.     

Stock return seasonalities and investor structure: Evidence from China's B-share markets

This paper investigates whether seasonalities in daily stock returns are related to the trading behavior of individual and institutional investors. The change in the investor structure of B-share markets in Shanghai and Shenzhen after the abolition of ownership restrictions in 2001 provides a unique testing environment. We show that day-of-the-week effects are attenuated after the market entrance of Chinese individual investors who had previously not been allowed to trade in B-shares. Our empirical results suggest that institutional rather than individual investors are a main driving force behind such anomalies. In addition, we find evidence of reduced index return autocorrelation and US spillover effects in the post-liberalization period.     

A dynamic game for fiscal federalism with non-local externalities

We address the questions of the patterns and the efficiency of public intervention in a dynamic game model between public agencies in charge of a non-local externality. We give two examples: pollution spreading between water basins (negative externality), and non-uniform contributions from the elite and from the mass to a cultural background (positive externality). We define two extreme cases, depending on whether or not the receiving end of the externality balances the transmitting end. When both balance, the reactivity of the agency structure is strong and the need for redistribution between them is weak. When they do not balance, the externality is more markedly non-local and redistribution is required to balance the fiscal burden (or product) from pigouvian instruments among all beneficiaries. We show that, with a static rule of redistribution that allows them to compute transfers between them as a function of their own strategies, the decentralized agencies' reactivity is somewhat slowed, but they still react faster and more efficiently than a static central agency.     

Integration Among Asia‐Pacific and International Stock Markets: Common Stochastic Trends and Regime Shifts

Are stock markets in the Asia‐Pacific region integrated with each other and with the US and Japan? The paper examines a number of common stochastic trends among stock prices in the US, Japan, Hong Kong, Korea, Singapore, Taiwan and Thailand. If integration exists it is a fairly recent phenomenon. Institutional and economic considerations suggest the same is true so that a single common stochastic trend among Asian and North American markets is a recent phenomenon. The reason is that the stock markets studied were only recently sufficiently liberalized to permit some form of integration to emerge. Also, not only was the 1987 stock market crash significant, but the 1991 Gulf War also signalled a turning point in the degree of stock market integration among the countries studied.     

The Global Leadership Life Inventory: development and psychometric properties of a 360-degree feedback instrument

The purpose of this paper is to describe the design of Global Leadership Life Inventory (GlobeInvent), a 360-degree leadership feedback instrument. This instrument is presently used in executive programmes to help identify the operational mode of individual executives. Proper use of this instrument enables the user to determinate those areas of leadership behaviour where improvement is needed.

Because most studies pay attention only to the surface manifestations of leadership, most leadership feedback instruments, in turn, are not concerned with the psychodynamic processes that underlie leaders' character and behaviour. To address this gap, the GlobeInvent is based on a clinical orientation to the study of leadership. This approach provides a more complete analysis of the ‘inner theatre’ of leaders?–?that is, what makes them tick?–?as well as measuring the dynamic, two-way relationship between leaders and followers.

The first step in designing the instrument was to pinpoint significant themes pertaining to exemplary leadership. To that end, semi-structured interviews with senior executives were held. The leadership dimensions that emerged from that process were then tested on an international sample of senior executives. Analysis of the data from the testing confirmed the existence of twelve robust dimensions with a high reliability and internal consistency.

Because the GlobeInvent is a 360-degree feedback instrument, this article addresses differences between ‘Self’ scores and scores given by others (‘Observers’), gender differences in scoring and the influence of nationality, management experience and age on test results. The implications of using such an instrument as a 360-degree feedback tool are reviewed, and suggestions for future research are offered.     

On the Applicability of the Sieve Bootstrap in Time Series Panels*

In this article, we investigate the validity of the univariate autoregressive sieve bootstrap applied to time series panels characterized by general forms of cross‐sectional dependence, including but not restricted to cointegration. Using the final equations approach we show that while it is possible to write such a panel as a collection of infinite order autoregressive equations, the innovations of these equations are not vector white noise. This causes the univariate autoregressive sieve bootstrap to be invalid in such panels. We illustrate this result with a small numerical example using a simple DGP for which the sieve bootstrap is invalid, and show that the extent of the invalidity depends on the value of specific parameters. We also show that Monte Carlo simulations in small samples can be misleading about the validity of the univariate autoregressive sieve bootstrap. The results in this article serve as a warning about the practical use of the autoregressive sieve bootstrap in panels where cross‐sectional dependence of general form may be present.     

Quel prix pour la sécurite alimentaire? Une évaluation contingente suite à la crise européenne de la ≪ vache folle ≫

L'hypothèse d'une éventuelle contamination humaine par la maladie de Creutzfeldt‐Jakob, par le biais du prion de I'encéphalite spongiforme bovine (ESB), faite en 1996 par le ministre de la santé anglais a étéè l'origine d'une perte de confiance des consommateurs dans la viande de b?uf. Lew comportement en France a étéétudié a partir d'une enquête menée en 1997, auprés d'un échantillon représentatif de 700 personnes résidant dans l'agglomération de Rennes en Bretagne. L'enquête présente aux personnes interrogées un scénario contingent visant èévaluer leur consentement è payer (CAP) afin de disposer d'une viande pour laquelle tout risque de contamination par l'ESB est écarté. Un processus original de révélation des CAP a été utilisé, combinant la méthode du référendum et un système d'enchères. Le CAP moyen obtenu est relativement élevé puisqu'il atteint 22 % du prix initial de la viande. Un modéle micro‐économique visant è expliquer la valeur du CAP du consommateur pour une sécurité alimentaire totale par rapport è l'ESB est alors présenté. De cette formalisation micro‐economique découle une spécification économétrique correspondant au modele multinomial logit ordonnéè seuils connus. Parmi les variables ayant un role determinant dans le choix du CAP des consommateurs figurent notamment la confiance dans les indications géographiques et les labels. After the British Minister of Health admitted a possible link between the BSE prion and the Creutzfeldt‐Jakob disease in 1996, consumers lost confidence in the beef sector. This paper analyses consumers behavior after the BSE crisis in France in 1997, based on a survey using a random sample of 700 people located in the area of Rennes (Bretagne). Particularly, a contingent scenario was proposed to the respondents to elicit their willingness to pay (WTP) to have beef which would not transmit CJD using a mix of the referendum method and the bidding process. The mean WTP reaches 22% and is consistent with results obtained in other studies. A microeconomic model is proposed and an econometric approach based on an ordered logit model is developed. Among the significant variables, it is interesting to note the role of stamps of quality to explains consumers'behavior. Such variables prove the interest of a transparency and tracability policy to restore the consumers confidence.     

Some Obscurities in Indonesia's New National Accounts

Indonesia's national accounts are subject to regular revisions. Some of these revisions have resulted in different estimates of GDP on both the output and the expenditure side of the economy in overlapping years. Unfortunately, the explanations accompanying the published national accounts make it difficult to understand the exact reasons why this is so. This article explores the possible explanations. It also discusses the consequences of changes to the base year used in the calculation of constant price series. The paper draws attention to several new national accounting initiatives developed at Indonesia's Central Statistics Agency that underscore the Agency's advanced professionalism in national accounting. It concludes with a call for greater openness in explaining national accounting procedures.
