1. 1 INTRODUCTION The final chapter of my Personal Income Distribution, a Hulticapability Theory (Hartog, 1981a) carried as its motto: 'Oh richness of the unfinished'. It concluded a book in which labor services were decomposed into services arising from different capabilities. Individuals were supposed to command stocks of capabilities and to decide on the utilization rates of these capabilities, by balanc ing efforts and rewards. The optimal capability bundle they so defined was to be realized by picking the job that just required this bundle. To derive analytical implications on the structure of the labor market and on the distribution of labor earnings, the key assumption was made that arbitrage in capability supply was possible, i. e., that effectively capabilities could be sold separ ately and carried a uniform unit price throughout the labor market. While many interesting analytical and empirical results followed, there was also an indication from empirical testing that an earnings function linear in capabilities could be outperformed by a non-linear func- 2 CAPABILITIES, ALLOCATION AND EARNINGS tion, and that the arbitrage assumption might be un tenable. This book attempts to harvest a little from the richness of the unfinished that was left. It returns to some of the old topics and adds some new ones, in a more general model that no longer imposes the assumption that capabilities can be treated as if they can be unbundled. It also draws on new datasets to explore the issues empirically."

Economists measure the effects of immigration through the yardstick of income. This book offers a broad survey of the conventional approach but in addition, also considers better measures of welfare or well-being and provides a detailed description and evaluation of policies - rules, regulations and implementation. The book offers a long, historical perspective on the development of population density in the Netherlands. It begins with the history of the Netherlands: geological and cultural formation of the land - and water - and population development. The Netherlands is unique in that much of the land is man-made, in particular the western part, which is, economically speaking, the most developed area. It is also special for its very high population growth rate that took off during the 19th century. The key argument of the book is that population size is irrelevant for income per capita, that land is a binding constraint in the Netherlands and that negative external effects of increasing population size lead to welfare losses from further population growth, whether by natural growth or by immigration. At present, the battle for scarce land is intense and bitter, with a strong clash between developers who want to build houses, farmers who do not want to give up farming and conservationists who increasingly find support in the courts for insufficiently caring for the natural environment. The book combines a general analysis of population density, both theoretical and empirical, with an in-depth presentation of actual policies in a country with intense pressure on available land.

At a time when governments and policy-makers put so much emphasis on 'the knowledge economy' and the economic value of education, human capital theory has never been more important. However, research in this area is often very technical and therefore not easily accessible to those who wish to use it as a guide to policy formation. This book provides an interface between such research and its potential applications in government, education and business. Reporting on a major research initiative, new findings are presented in a non-technical way on three major themes: measuring the benefits from human capital, applications of the human capital model, and policy interventions. Aimed at academic researchers and professionals concerned with the problems and techniques of human capital theory, it will also be useful for graduate courses on the economics of education to complement standard textbooks.

The authors present important research showing that corporatist institutions generate smaller non-competitive wage differentials than a decentralized system. A theoretical explanation is developed based on the hold-up problem in investments, arguing that corporatist institutions solve the problem by specifying ex ante nominal contracts that remove the necessity of ex post bargaining over the surplus of an employment relationship. The authors also argue that such institutions allow sufficient flexibility to accommodate aggregate shocks, even more so than decentralized systems. Corporatism or Competition? is the first book to bring together the mass of research on comparative wage differences, wage movements and employment behaviour in different countries with different institutional frameworks, in an organized and coherent fashion.
