Unity in diversity? The creation of new local governments in a decentralising Indonesia

This paper evaluates the proliferation of local governments concurrent with Indo-nesia's 2001 decentralisation. Largely static for decades under the New Order, the number of municipalities (kota) and districts (kabupaten) has increased by half, from 292 before decentralisation to 434 in 2003. Most of the increase is off-Java. This represents a fundamental change in Indonesia's subnational administrative, political and fiscal landscape. We present a new dataset that elucidates the characteristics of these new kota and kabupaten, and review political, fiscal and economic incentives for creating new jurisdictions. We find that geographic dispersion, political and ethnic diversity, natural resource wealth and scope for bureaucratic rent seeking all influence the likelihood of regional splits. Since jurisdictional changes will affect local governance and service delivery, we stress the importance of providing an effective institutional framework for the creation – or future amalgamation – of local governments as part of a strategic approach to consolidating Indonesia's decentralisation.     

Performance evaluation of portfolio insurance strategies using stochastic dominance criteria

This paper evaluates the performance of the stop-loss, synthetic put and constant proportion portfolio insurance techniques based on a block-bootstrap simulation. We consider not only traditional performance measures, but also some recently developed measures that capture the non-normality of the return distribution (value-at-risk, expected shortfall, and the Omega measure). We compare them to the more comprehensive stochastic dominance criteria. The impact of changing the rebalancing frequency and level of capital protection is examined. We find that, even though a buy-and-hold strategy generates higher average excess returns, it does not stochastically dominate the portfolio insurance strategies, nor vice versa. Our results indicate that a 100% floor value should be preferred to lower floor values and that daily-rebalanced synthetic put and CPPI strategies dominate their counterparts with less frequent rebalancing.     

Exclusivity Contracts,Insurance and Financial Market Foreclosure

We study the trade‐off between the positive effects (risk‐sharing) and negative effects (exclusion) of exclusivity contracts. We revisit the seminal model of Aghion and Bolton [ 1987 ] under risk‐aversion and show that although exclusivity contracts induce optimal risk‐sharing, they can be used not only to deter the entry of a more efficient rival into the product market but also to crowd out financial investors willing to insure the buyer at competitive rates. We further show that in a world without financial investors, purely financial bilateral instruments, such as forward contracts, achieve optimal risk‐sharing without distorting product market outcomes. Thus, risk‐sharing alone cannot be invoked to defend exclusivity contracts.     

Innovation in food firms: contribution of regional networks within the international business context

This paper explores the role of regional networks in processes of innovation within an international business context. It is hypothesized that firms participating in regional networks demonstrate a stronger innovation competence. Data are drawn from a survey among food firms in the region of Meetjesland, Belgium, and reflect the relation between the firm and a number of regional characteristics. After restructuring the data through factor analysis and cluster analysis, the important role of regional networking is revealed using discriminant analysis. The analysis marks out two factors having the strongest power to discriminate between the clusters: firms are classified as having a stronger innovation competence when networking within the region, and when orienting towards the international market. Results demonstrate that internationally operating firms benefit from regional networking. Further, it is argued that regional networking is not contradictory to an international market orientation, and that firms gain innovation competence by searching for external knowledge on different geographical scales. As these networks have the potential to enhance the innovation competence of firms, support to regional networking is promoted as a policy tool.     

VOLATILITY TRANSMISSION AND PATTERNS IN BUND FUTURES

We analyze intraday volatility behavior for the Bund futures contract that is traded simultaneously at two competing exchanges. We investigate the transmission of volatility between the exchanges. We find that the lead/lag relations are restricted to a few minutes and do not reveal a dominant leader. We then analyze patterns in intraday volatility. We find that volatility behaves similarly at both exchanges; i.e., it decreases from the opening until early afternoon and increases thereafter. The same pattern is detected in explanatory variables such as traded volume and time-between-trades.     

Computer-based adaptive testing in 1991

Tests, questionnaires, and inventories can advantageously be administered by computer. The use of item response theory (IRT) is described, and its application to making the instruments adaptive. Practical aspects of adaptive tests are discussed, including timing and safeguarding. Adjustments can be made for mastery tests. More elaborate partial-credit models are needed for items with more than two response alternatives.     

Size,Growth, and Variance among the World's Largest Non-merged Banks

This paper analyses growth, size, and variance of the capital, assets, and pre-tax profits of large international banks during 1987-97.We test hypotheses on whether size matters. It turns out that there is an inverse relationship between the amount of bank capital, assets, and profits and the growth rate of these items.This is in line with the findings for US banks in the pre-BrettonWoods era. Furthermore, we did not find, in contrast with Tschoegl's observations for international banks in the 1970s, a negative relationship between the size of large banks and the variability of growth in capital, assets, or profits. We conclude that size is not a self-sustaining attribute of international banks.
