Child care voucher and labour market behaviour: experimental evidence from Finland

This article provides experimental estimates of the impact of a voucher for private care on labour force participation and use of private and public child care within the Nordic system of universal provision of public care. In a market that was providing high-quality, low-cost public child care, a voucher is nevertheless found to have a significant, positive effect for the use of private child care with zero effects on either use of public care or labour force participation. The use of private increased by five percentage points in the whole country and by five to seven percentage points in areas that suffer from excess demand for child care as a result of the introduction of the private child care voucher.     

The theoretical and empirical evaluation of the third world brain drain to the United States: 1972-1987

"This paper is divided into four sections. Section I deals with theoretical issues behind labor migration in general with emphasis on 'brain drain'. Section II is concerned with an empirical analysis of third world professional immigration into the U.S. for the time period 1972-1987. Section III discusses policy implications to deal with [the] 'brain drain' problem."     

Mokken scale analysis for polychotomous items: theory,a computer program and an empirical application

This paper contains three subjects. First, an extension of Mokken's nonparametric item response models from dichotomous items to items with two or more ordered answer categories is proposed. Second, a computer program to analyze multicategory item scores is presented. This program is called MSP. The analyses by means of MSP are based on the multicategory extension of Mokken's theory. Finally, an application of MSP to empirical multicategory test data is presented in order to illuminate its possibilities.     

Death is not an option, how you die is--reflections from a career in oncology nursing

With a combined career of over 60 years in oncology nursing, the authors reflect on the critical elements in the question, "How can we afford to die?" Three high-profile patient scenarios in three different decades promised to improve use of advance directives but did not. Recent societal events, including the debates about health care reform, have brought attention again to end-of-life issues and care. Quickly approaching a "perfect storm" of an aging population, an inefficient and costly illness-oriented health care system, and health care profession shortages, the United States will not be able to afford delivering futile interventions. Nurses, who are consistently seen as the most trusted professionals, must take action in strategies the authors present.     

Fundraising and Optimal Policy Rules

This paper develops a simple spatial model of fundraising, in which charities select a target population to solicit donations. First, we show that in a competitive charity market without any intervention, the number of charities in the market and/or the overall net funds raised by charities may be suboptimal. Next, we analyze whether a social planner can prevent such shortcomings and show that a regulatory mechanism can be designed to achieve socially desirable outcomes. In contrast to the previous literature, our model does not necessarily produce monopoly as the optimal market structure. We show that if fixed costs associated with establishing charities are sufficiently low, then the optimal market structure is not a monopoly. Given the importance of the trade‐off between the volume and variety of charitable services, we argue that this result may be of particular interest to policy makers.     

Optimal policy with credibility concerns

This paper considers a reputation model of optimal taxation in which the public is unsure about the government type. A long-lived government can be trustworthy (meaning that it commits to its announced tax rate) or opportunistic (meaning that it retains the ability to change its tax rate after announcing it). Unlike in most prior studies, the committed strategy in this model is optimally chosen by the trustworthy type. We show that this change has significant consequences for the equilibrium dynamics. The optimal committed strategy is found to vary with the time preferences of the two government types, the initial reputation of the government, and the elasticity of household production. This formulation explains differences in policy responses across governments in the face of similar credibility problems.     

Collective Choice and Control Rights in Firms

Recent writers have asserted that firms controlled by workers are rare because workers have diverse preferences over firm policies, while investors all support wealth maximization. However, the source of the asymmetry between capital and labor remains unclear. We resolve this puzzle by arguing that because financial capital is exceptionally mobile, capital markets induce unanimity. The lower mobility of human capital implies that labor markets are monopolistically competitive and hence that unanimity cannot be expected in labor‐managed firms. Moreover, such firms are vulnerable to takeover by investors, while capital‐managed firms are substantially less vulnerable to takeover by workers.     

Testing spatial regression models under nonregular conditions

In time series context, estimation and testing issues with autoregressive and moving average (ARMA) models are well understood. Similar issues in the context of spatial ARMA models for the disturbance of the regression, however, remain largely unexplored. In this paper, we discuss the problems of testing no spatial dependence in the disturbances against the alternative of spatial ARMA process incorporating the possible presence of spatial dependence in the dependent variable. The problems of conducting such a test are twofold. First, under the null hypothesis, the nuisance parameter is not identified, resulting in a singular information matrix (IM), which is a nonregular case in statistical inference. To take account of singular IM, we follow Davies (Biometrika 64(2):247–254, 1977; Biometrika 74(1):33–43, 1987) and propose a test procedure based on the supremum of the Rao score test statistic. Second, the possible presence of spatial lag dependence will have adverse effect on the performance of the test. Using the general test procedure of Bera and Yoon (Econom Theory 9:649–658, 1993) under local misspecification, we avoid the explicit estimation of the spatial autoregressive parameter. Thus our suggested tests are entirely based on ordinary least squares estimation. Tests suggested here can be viewed as a generalization of Anselin et al. (Reg Sci Urban Econ 26:77–104, 1996). We conduct Monte Carlo simulations to investigate the finite sample properties of the proposed tests. Simulation results show that our tests have good finite sample properties both in terms of size and power, compared to other tests in the literature. We also illustrate the applications of our tests through several data sets.
