Price uncertainty and the effect of capital costs in a point in-point out inventory investment

This paper analyzes a point in-point out inventory investment under price uncertainty. The optimal quantity is determined by maximizing the expected value of the investor's risk preference function, which is a function of profit. Using an exponential risk preference function, the adjustment in the optimal quantity stemming from a change in the interest rate is investigated. The main conclusion is that the sign of the adjustment depends both on how profit is expressed and on the type of price distribution applied. Contrary to what is assumed in conventional managerial control practices, a rise in the interest rate might lead to an increase in the optimal quantity when present value serves as a measure of profit.     

ON THE FIRST–ORDER EFFICIENCY AND ASYMPTOTIC NORMALITY OF MAXIMUM LIKELIHOOD ESTIMATORS OBTAINED FROM DEPENDENT OBSERVATIONS

Abstract. In this paper we study the first–order efficiency and asymptotic normality of the maximum likelihood estimator obtained from dependent observations. Our conditions are weaker than usual, in that we do not require convergences in probability to be uniform or third–order derivatives to exist.
The paper builds on Witting and Nolle's result concerning the asymptotic normality of the maximum likelihood estimator obtained from independent and identically distributed observations, and on a martingale theorem by McLeish.     

Testing for Vertical Fiscal Externalities

The purpose of this paper is to design a test of whether the vertical external effects associated with tax base sharing among local and regional governments have become internalized via the intergovernmental transfer system. Such tests are important in the sense that the income tax rates chosen by different levels of government will generally be correlated, even if the resource allocation is optimal from society's point of view. By using panel data for the Swedish local and regional public sectors, the results imply that an increase in the regional income tax rate induces the municipalities in the region to decrease their income tax rates. In addition, we are able to reject the null hypothesis that the vertical external effects have become internalized.     

Entrepreneurship and the theory of taxation

A review of the literature on firm taxation reveals that the economics of entrepreneurship has not sufficiently been taken into consideration. We discuss how this affects conclusions derived from standard models of capital taxation when applied to entrepreneurial income. Some defining features of entrepreneurship important for analyzing the effects of taxation of owner-managed firms are identified. These include the lack of a well-functioning external market for entrepreneurial effort, limited access to external capital and complementarities between entrepreneurial innovation, effort and capital. Due to these constraints, the entrepreneurial project is tied to the individual owner–manager. The entrepreneur is unable to decouple saving decisions from investment decisions, and makes joint decisions on the supply of effort and capital. The return from successful entrepreneurial ventures can therefore not be readily divided into labor and capital income, in deep contrast to what is typically assumed in taxation theory. It is argued that when distinct attributes of entrepreneurship are taken into account, certain conclusions of capital taxation models may no longer hold, including the neutrality of capital taxation in owner-managed firms. Cost of capital formulas derived from the behavior of public firms could underestimate distortions when applied to the investment behavior of entrepreneurial firms. For tax purposes and otherwise, it becomes useful to analyze return to entrepreneurial activity as income of a distinct factor of production. In this context, conceptual issues and the difficulties of measuring entrepreneurial income are discussed.     

Multinational Corporations and Spillovers

This paper examines spillover effects of the activities of multinational firms. Such effects are most likely to be found in host countries, where the operations of foreign multinationals may influence local firms in the MNCs own industry as well as firms in other industries. However, there is no comprehensive evidence on the exact nature or magnitude of these effects, although it is suggested that host country spillovers vary systematically between countries and industries. In particular, the positive effects of foreign investment are likely to increase with the level of local capability and competition. The spillovers to the home countries of MNCs are often more difficult to identify, for various reasons. Earlier studies suggest that the effects are generally positive, but the increasing international division of labor within multinationals complicates the analysis. The impact on the home country is likely to depend on what activities these firms concentrate at home.     

From the Soviet Union to the European Union: Estonian Trade Policy, 1991–2000

This paper examines the political economy of Estonian trade policy in the 1990s. Estonia is a unique case in the world economy, in that the country rapidly implemented unilateral free trade after regaining independence and sustained it right through the 1990s. We analyse the circumstances, interests, ideas and institutions that have shaped Estonian trade policy during the past decade. Our stress is on institutions, particularly the national decision‐making setting for trade policy. Through this prism we try to understand how a free trade regime was implemented and sustained, and what this experience suggests for the feasibility of tree trade elsewhere. We also look at the increasingly ‘multi‐track’ nature of Estonian trade policy through bilateral free trade agreements, WTO accession and, especially, the movement towards EU accession. Although the other trade policy tracks to some extent provide a lockin for unilateral reforms, we argue that EU accession is undermining the simple, classical liberal trade policy regime that existed during the 1990s.     

The innovating region: toward a theory of knowledge-based regional development

This paper sets forth a model of knowledge-based regional development conceived as a set of multi-linear dynamics, based on alternative technological paradigms. Utilizing longitudinal data from a Swedish region, and international comparisons, four stages of development are identified: Inception, Implementation, Consolidation and Renewal. Innovation policy is created 'bottom-up' as an outcome of 'collective entrepreneurship' through collaboration among business, government and academic actors – the 'triple helix'. The key event is the creation of an entrepreneurial university, whether from an existing academic base or a new foundation, which takes initiatives together with government and industry to create a support structure for firm formation and regional growth. The result of these initiatives is a self-sustaining dynamic in which the role of academia and government appears to recede as industrial actors come to the fore and a lineage of firms is created. Nevertheless, as one technological paradigm is exhausted and another one is needed as the base for new economic activity, the role of academia and government comes to the fore again in creating the conditions for the next wave of innovation.     

Die niederländische Gesundheitsreform 2006 – Vorbild für eine weitere Reform des Krankenversicherungswesens in Deutschland?

The health sector of many European countries has been subject of a profound process of change for years. Since the federal elections of 2009 a discussion on the direction of the German health insurance system has emerged. In this context, German neighboring countries like Switzerland or the Netherlands are considered due to their changes in health policy for decades. This work deals with the effects of the recent Dutch health care reform. Due to the combination of the two elements “Bürgerversicherung” and “Kopfpauschale”, it serves as a possible model for further reform in the German health system since its introduction in 2006. Special attention was paid to the consolidation of statutory and private insurance in a general citizens insurance in the Netherlands “three-pillar model”. Because of the medium-term time horizon, financial impacts on state and private households and changes in competition between insured individuals, insurers and providers could be analysed. Especially, positive effects in terms of increasing competition and reducing the two-tier health care became apparent.     

Concept‐Based Bayesian Model Averaging and Growth Empirics

In specifying a regression equation, we need to specify which regressors to include, but also how these regressors are measured. This gives rise to two levels of uncertainty: concepts (level 1) and measurements within each concept (level 2). In this paper we propose a hierarchical weighted least squares (HWALS) method to address these uncertainties. We examine the effects of different growth determinants taking explicit account of the measurement problem in the growth regressions. We find that estimates produced by HWALS provide intuitive and robust explanations. We also consider approximation techniques which are useful when the number of variables is large or when computing time is limited.
