Nonparametric tests of collectively rational consumption behavior: An integer programming procedure

We present an IP-based nonparametric (revealed preference) testing procedure for rational consumption behavior in terms of a general collective model, which includes consumption externalities and public consumption. An empirical application to data drawn from the Russia Longitudinal Monitoring Survey (RLMS) demonstrates the practical usefulness of the procedure. Finally, we present extensions of the testing procedure to evaluate the goodness-of-fit (accounting for optimization error as well as measurement error) of the collective model subject to testing.     

Coevolution of economic behaviour and institutions: towards a theory of institutional change

Traditionally, economics has regarded institutions, notably norms and regulations, as fixed or exogenous. Surprisingly few insights on institutional evolution from natural and social sciences have made their way into economics. This article gives an overview of evolutionary theories of institutions in biology, sociology, anthropology and economics. These theories are subsequently compared with non-evolutionary theories of institutions. Next, the insights and approaches are integrated into a framework for analysis of institutions based on the notion of coevolution.JEL Classification: B52, D10, D70, D64, Z13J.C.J.M. van den Bergh     

Empirical relevance of the Hillman condition for revealed comparative advantage: 10 stylized facts

The theoretically necessary and sufficient condition for the correspondence between ‘revealed’ comparative advantage and pre-trade relative prices derived by Hillman (1980 Hillman, AL. 1980. Observations on the relation between ‘revealed comparative advantage’ and comparative advantage as indicated by pre-trade relative prices. Weltwirtschaftliches Archiv, 116: 315–21. [Crossref] , [Google Scholar]) is analysed empirically for virtually all countries of the world over an extended period of time. This yields 10 stylized facts, including that (i) violations of the Hillman condition are small as a share of the number of observations, but substantial as a share of the value of world exports, (ii) violations occur relatively frequently in the period 1970–1984 and more rarely in the period 1985–1997 and (iii) violations occur foremost in primary product and natural resource intensive sectors and for countries in Africa, the Middle East, Latin America and Central and Eastern Europe. An additional bonus of verifying the Hillman condition in empirical research is its ability to identify erroneously classified trade flows.     

Global equity fund performance, portfolio concentration, and the fundamental law of active management

This paper investigates the relation between portfolio concentration and the performance of global equity funds. Concentrated funds with higher levels of tracking error display better performance than their more broadly diversified counterparts. We show that the observed relation between portfolio concentration and performance is mostly driven by the breadth of the underlying fund strategies; not just by fund managers’ willingness to take big bets. Our results indicate that when investors strive to select the best-performing funds, they should not only consider fund managers’ tracking-error levels. More important is that they take into account the extent to which fund managers carefully allocate their risk budget across multiple investment strategies and have concentrated holdings in multiple market segments simultaneously.     

Preference hierarchies for internal finance, bank loans, bond, and share issues: evidence for Dutch firms

We estimate the incremental financing decision for a sample of some 150 Dutch companies for the years 1984 through 1997, thereby distinguishing internal finance and three types of external finance: bank borrowing, bond issues, and share issues. First, we estimate a multinomial logit model, which confirms several predictions of both the static trade-off theory and the pecking order theory as to the determinants of financing choices. Next, we estimate all possible ordered probit models to determine which financing hierarchy fits the data best. The results suggest that Dutch firms have a unique most preferred financing hierarchy: (i) internal finance, (ii) bank loans, (iii) share issues, and (iv) bond issues.     

Subsidizing cooperative and noncooperative R&D in duopoly with spillovers

Comparing the effect on private R&D investments of allowing firms to cooperate in R&D with that of providing R&D subsidies reveals that in general the latter policy is more effective than the former in promoting R&D activity. Analyzing the implementation of both policies simultaneously reveals that subsidizing cooperative and noncooperative R&D leads to the same market outcome. The preferred R&D-stimulating policy is to subsidize optimally an agreement according to which firms only share the outcomes of their independent research.

The effect of audit market structure on audit quality and audit pricing in the private-client market

This study examines whether audit market structure affects audit quality and audit pricing. We analyze two conceptually distinct dimensions of market structure: audit market concentration and client mobility. Focusing on the private-client segment of the Belgian audit market, we compare the pricing and quality effects of market structure between the segment of small and medium-sized (SME) clients and the segment of large clients to test how audit complexity moderates such effects. We find that market concentration impairs price and quality competition in the SME-client segment. Market concentration is unrelated to audit quality in the large-client segment, where we argue that concentration is endogenous to audit complexity. Furthermore, we find that client mobility stimulates price competition in both segments but improves audit quality only in the large-client segment. We interpret our findings as evidence that (a) audit market concentration impairs competition especially when audits have low complexity and that (b) the large-client market segment, characterized by higher audit complexity and higher market concentration, can also be price and quality competitive if clients are sufficiently mobile, and change auditors relatively frequently.     

Employment growth and innovation at the firm level

We analyze the influence of innovation on growth rates of employment in 859 Dutch manufacturing firms over the period 1983–1988. Whereas the (growth of the) R&D intensity of firms has a slightly negative impact on employment, we find that firms with a high share of product-related R&D (as a proxi of R&D related to industrial activities in an early stage of the life cycle) experienced an above average growth of employment. The same holds for firms which directed their R&D towards information technology. Smaller firms have, ceteris paribus, substantially higher growth rates of employment than their larger counterparts. Against our expectations, R&D cooperation has no significant impact on employment growth. The same holds for activities in the fields of biotechnology and new materials.     

A framework for modelling economy-environment-development relationships based on dynamic carrying capacity and sustainable development feedback

A large literature exists that deals with economic issues of development and growth. It includes various approaches that can be classified as formal-theoretical, empirical-statistical and qualitative-verbal. Recently, the issue of sustainable development has been discussed much, which has given rise to some novel views on the relationship between development and environment. Most of these contributions utilize a more or less qualitative approach. A comprehensive inquiry of the relationship between economy, development, growth and environment may include an analytical approach as well. An analytical framework is proposed here for studies of environment-economy-development relationships that separates between economy, development, environment, and value system. A distinction is made between direct and indirect economy-environment interactions. To overcome disadvantages of assumptions of determinism in long term analysis a sustainable development feedback mechanism is proposed. It reflects anticipative behaviour to natural environmental changes in making long term decisions. This can be seen as a specific element of endogenous growth, namely one based on environmental factors. To illustrate the ideas a number of theoretical models are discussed that can be regarded as dynamic formal extensions of the concept of carrying capacity. Different cases include combinations of internal and external feedback mechanisms to an economy. The results demonstrate that in addition to behaviourial patterns that have been obtained by more complex studies other patterns may emerge.This study was supported by the Economic Research Foundation (Ecozoek), which resorts under the Netherlands Organization for Scientific Research (N.W.O.), project no. 450-230-007.This paper is based on reprocessed material from my Ph.D. dissertation.
