Employment,schooling and productivity growth

Summary This paper presents an empirical analysis of labour demand and labour productivity growth in The Netherlands. Assuming an aggregate production function with as factors capital and 3 types of labour, distinguished by educational attainment, cost minimization leads to a set of 3 labour demand relations to be estimated on time series data. Using the estimates and the implied elasticities, aggregate labour productivity growth is decomposed into factor substitution, autonomous factors, labour time shortening, economies of scale, utilization rates and the increased educational level of the working population. The contributions of substitution, utilization rates and education appear to be substantial, notably in the seventies.

Hiring functions and a new index for measuring mismatch: Some empirical results for european countries

Conclusion This paper investigates the relation between mismatch and sectoral hiring functions. Traditionally, the indices used to measure structural mismatch were constructed by assuming that the hiring functions are identical across sectors. However, both theoretically and empirically, there is no reason to believe that the hiring behavior of the firms or the search methods of the workers are identical across sectors. Evidence for this is provided in the Appendix of this paper where it is shown that theUV curves for the different regions in Great Britain and different sectors in Switzerland are not identical. Brunello [1990] also shows that the hiring functions do not have to be identical. This paper also demonstrates that it may not be possible to eliminate structural unemployment totally when the hiring functions across sectors are non-identical. In other words, total hiring may be maximized even if theV/U ratios are not equalized across sectors. This conclusion is important as it highlights that the indices used in empirical work to measure structural mismatch may be seriously flawed.This paper develops an index for measuring mismatch which is rooted in the theory of hiring functions and utilizes the approach of measuring angle between vectors by the use of cos() functions. The FH index presented in this paper is based on a simple arithmetic mean of regional or sectoral cos() functions. It has been estimated for several European countries, and the empirical results highlight some interesting conclusions concerning regional mismatch in these countries.     

Wicksell's version of Gibson's Paradox

Summary Knut Wicksell's theory of price increase depends on a positive two-rate-interest-differential between the natural (i _N ) and the loan rate (i _L ). It is shown how Wicksell uses this theory to justify the positive relation over time between prices and the nominal interest rate now called Gibson's Paradox. Bothi _N andi _L must be stated in nominal terms and an independent increase ini _N sets off the increase in P.i _L remains constant for a time, while the nominal demand for credit increases.i _L eventually increases after a substantial lag with respect to the increase in P. The rate of inflation rather than the price level is also brought in as a potential cause ofi _L rising.He wishes to acknowledge the support of the Avron B. and Robert F. Fogelman academic excellence fund, which made the writing of this paper possible.     

Trade uncertainty and specialization. Social versus private planning

Summary A small trading economy which produces and trades an arbitrary, but finite, number of goods and faces given terms of trade in combination with an uncertain volume of trade is studied. An exogenous probability of trade disruption forces both public and private decision-makers to specialize to a lesser extent in accordance with their comparative advantage. A unique optimal point of production exists for each probability of trade disruption. A private competitive economy will not produce at this point: it produces too much of the good with a comparative advantage.Notation C ² class of twice continuously differentiable functions - C _i consumption of goodi - f free-trade utility function - g autarky utility function - p international relative price of goody - p _d domestic relative price of goody - Q solution set of - U utility function - U marginal utility of goodi - U _x marginal utilities of lastn goods - x goodx - x ^* autarky production of goodx - x free-trade production of goodx - x _pr private production of goodx - x ₀ optimal production of goodx - x _m maximal production of goodx - y goody - Y income function - private economy equilibrium function - difference function - production possibility function - _x derivative of - probability that free trade occurs - indirect utility function - solution function to optimality problem - c consumption vector - p relative price vector - x goods vector - t transpose - R ₊ ⁿ n-dimensional positive orthant This article communicates the opinion of the author.

Banks and the stability of the international financial system

Summary Does today's banking scene pose a potential threat to the stability of the international financial system? The article discusses three possible sources of vulnerability of the international banking system: a major bank failure causing a general banking crisis via the extensive interbank linkages; the systemic risks allegedly inherent in certain new (as well as traditional) financial products; and the impact of external events such as debt crises, violent swings in exchange or interest rates, deregulation and recession. The author's conclusion is twofold: systemic risks clearly exist, but the probability of a major banking crisis tends to be greatly exaggerated. Banks not only survived the various crises of the seventies and eighties; they also learned in the process. Capital and reserves have been strengthened, provisions for country risk and for general contingencies have increased, supervision has been tightened and it is exercised on a comprehensive as well as a world-wide consolidated basis (i.e. including all contingent and off-balance liabilities, and all offshore activities). Assuming reasonably intelligent policies on the part of the monetary authorities and adequate international coordination, a general banking crisis can be avoided. Official rescue operations do, however, raise difficult questions of an ethical, political and economic nature.     

Disability Insurance Denial Rates and the Labor Force Participation of Older Men and Women in Canada

We examine the effect of denial rates from the Canada/Quebec Pension Plan (C/QPP) disability program on the labor force participation of older men and women in Canada. Our study uses data from a period in which there was a change in CPP disability adjudication requirements, which also varied by province, but no change in the QPP disability program requirements. This created variation in the CPP disability program’s denial rates. The estimates from our preferred specifications indicate that denial rates do not have the expected statistically significant negative effect on the participation decisions of older men or women. These findings may be the result of a change in the applicant pool for disability benefits.

The market as a commons: Is catching customers like catching fish?

Summary This note is a critique of an article by P. Copes published in the February 1984 issue ofDe Economist. Copes argues that an open access market must be regarded as a common property resource. By analogy to the economics of the fishery, he derives the proposition that free access to any market results in excess capacity because competitive entry dissipates what he calls the market rent. Copes claims that his results hold for the limiting case of perfect competition. Our critique explains why the analogy between a perfectly competitive market and a open access fishery is invalid.     

Post- war European economic development as an out of equilibrium growth path. The case of the Netherlands

The paper examines a number of aspects of post-war economic development of the Netherlands in the light of recent out of equilibrium growth theory. It contains a comparison of the stylized facts of the long run performance of the economies of the United States and the Netherlands which suggests that the US has been on an equilibrium growth path for more than a century, but that the Netherlands followed a radically different growth path, especially after 1945. It is attempted to explain this erratic behaviour of the investment ratio and the wage share after 1945 by examining two aspects more in detail: the financing of the acceleration of growth after 1945 and the phase of too rapid growth during the 1950s and 1960s, when the growth of the demand for labour tended to be higher than the increase in its supply.     

Een eenvoudig macro-economisch model voor Nederland

Summary On the basis of the neo-classical theory of the cycle, developed by D. B. J. Schouten, an effort has been made to introduce some of its elements in an empirical model for the Dutch economy. As far as possible this theory has been used to explain production, investment, employment and wages. The sampling period covered 1953–1965; estimates of the parameters were ordinary least squares estimates. A simulation of the Dutch economy for the period 1953–1968, with only the exogenous variables predetermined, gave satisfying results. System stability tests showed dampened oscillations, each cycle taking about 8 1/2 years.D Symbolenlijst c consumptieve bestedingen van gezinshuishoudingen (p _c ) - ç _a ,c _a bruto produktiecapaciteit van bedrijven (p _ij ) - e uitvoer goederen en diensten (p _e ) - h arbeidsproduktiviteit bij bedrijven (p _ij ) - ,i bruto investeringen van bedrijven, excl. woningbouw en voorraadvorming (p _i ) - l werkgelegenheid bij bedrijven, incl. zelfstandigen - m invoer goederen en diensten (p _m ) - p _i loonsom per man bij bedrijven (P _c ) - q over- of ondercapaciteit bij bedrijven als percentage van de bruto produktiecapaciteit in periodet-1 - v bruto afzet van goederen en diensten, excl. voorraadvorming, primaire inkomens van en naar het buitenland en lonen en salarissen betaald door de overheid (p _v ) - w werkloosheid als percentage van de afhankelijke beroepsbevolking, incl. zelfstandigen - ij bruto produktie van bedrijven (p _ij ) - z bruto beschikbaar overig inkomen (p _i ) Exogene variabelen h _w herwogen wereldhandel - x materiële overheidsuitgaven en woningbouw (p _x )     

Estimates of the Open Economy New Keynesian Phillips Curve for Euro Area Countries

This paper extends the existing literature on the open economy New Keynesian Phillips Curve by incorporating three different factors of production, domestic labor and imported as well as domestically produced intermediate goods, into a general model which nests existing closed economy and open economy models. The model is estimated for nine euro area countries and the euro area aggregate. We find that the general specification of our model improves the fit of the New Keynesian Phillips Curve considerably compared to the closed economy specification. The estimates of the structural parameters of the model suggest strong heterogeneity in the degree of price rigidity across euro area counties. Furthermore, we find the degree of price rigidity to be systematically lower in the open economy specification than in the closed economy specification and also lower than in the general specification of our model.

Smoke of leets

Summary This is a review of some of Mrs. Joan Robinson's ideas, and the author's conclusion is that these ideas do not contribute to the present state of economic theory. Her view on international trade is lopsided, her criticism of traditional capital theory goes too far, her refutation of income distribution theory is mainly unfounded. Basically, Mrs. Robinson rejects the notion of relative scarcity of capital; the author believes that this is a useful notion in economics. Moreover, her recent work shows a strong anti-empiricist tendency. If Mrs. Robinson's negative train of thought were to be applied to all concepts of macro-economic theory (total labour force, real national income etc.) these concepts would vanish in thin air. The whole of macro-economics might go up in smoke.     

Financial instability and the real economy

Summary The paper deals with three different areas of the financial sphere: national moneys, exchange rates and financial claims, markets and institutions. For each of them, it tries to identify the main forms of instability which may occur, their causes and consequences for the real economy. Depending on the area concerned, the forms of instability include inflation, fluctuations and misalignments in interest rates, exchange rates and asset prices and finally solvency and liquidity crises of institutions. It is concluded that, over the last fifteen years, significant progress has been made in the policy framework to counteract instabilities in the national and monetary spheres. The conclusion is more mixed with regard to the structure of financial markets.[/p]We are grateful to Julian Alworth, Svein Andresen, Gavin Bingham, Joe Bisignano, Michael Hutchison and Paul van den Bergh for useful comments.     

A Cointegration Model of Age-Specific Fertility and Female Labor Supply in the United States

Cointegration methods suitable for estimation and testing with nonstationary data are applied to U.S. time-series data on age-specific fertility rates, female labor force participation rates, women's wages, unemployment rates and educational attainment, and male relative incomes. Likelihood ratio tests indicate the existence of two cointegrating relations that are identified as a fertility equation and a labor supply equation, respectively. Estimated long-run relations are consistent with economic models of fertility and female labor market behavior, and these results are robust across both age-groups and several alternative model specifications.     

International labor-cum-capital migrations: Theory,welfare implications,and evidence

Although capital is often portrayed as being more internationally mobile than labor, the theory of labor migrations typically ignores capital flows. Economic historians provide long-term evidence suggesting close linkages between capital and labor movements for high labor immigration/emigration economies. Analyzing this linkage shows that labor-cum-capital migrations have distinctive economic effects compared to labor migrations alone. These distinctive effects impact on international economic economic convergence. GNP per head is invariably a poor indicator of development trends when labor (with or without capital) migrates.     

Strong Presidential Approval or Disapproval Influencing the Expected Benefits of Voting and the Voter Participation Rate

This empirical study seeks to broaden the interpretation of the rational voter model so as to identify and better understand key determinants of the expected benefits from voting and hence key determinants of the aggregate voter participation rate in the US. Using annual data for all years in the 1960–1997 study period, this study finds that the voter participation rate has been positively impacted by strong public approval or strong public disapproval of the incumbent President, a finding unique to this literature and study period. In addition, the aggregate voter participation rate has been positively impacted by such factors as the Gulf War, which is generally regarded as having been popular among the US electorate, and a rising unemployment rate. This study also finds the voter participation rate to have been negatively impacted by the publics dissatisfaction with government, as well as by the Watergate scandal.The author is indebted to Cassandra Copeland for helpful information, comments, and guidance.     

Estimated Open Economy New Keynesian Phillips Curves for the G7

In this paper we develop an open economy model of firms’ pricing behaviour under imperfect competition. This allows us to introduce various terms of trade effects influencing the firm’s pricing decision, in addition to labour costs which dominate most closed-economy specifications of the New Keynesian Phillips curve (NKPC). Our analysis gives rise to a hybrid open economy NKPC which nests existing closed and open economy specifications adopted in empirical work. We estimate this specification for the G7 economies and find that the US, UK and Canada typically enjoy less inertia in price setting than the European G7 economies and Japan and that these estimates are both plausible and in line with survey evidence. We also find that the proportion of firms which use simple backward-looking rules of thumb in price setting is greater when the frequency of price change is smaller. Finally there is evidence of significant asymmetries in price setting amongst EMU members.

Asset Prices in the Measurement of Inflation

The debate over including asset prices in the construction of an inflation statistic has attracted renewed attention in recent years. Virtually all of this (and earlier) work on incorporating asset prices into an aggregate price statistic has been motivated by a presumed, but unidentified transmission mechanism through which asset prices are leading indicators of inflation at the retail level. In this paper, we take an alternative, longer-term perspective on the issue and argue that the exclusion of asset prices introduces an excluded goods bias in the computation of the inflation statistic that is of interest to the monetary authority.We implement this idea using a relatively modern statistical technique, a dynamic factor index. This statistical algorithm allows us to see through the excessively noisy asset price data that have frustrated earlier researchers who have attempted to integrate these prices into an aggregate measure. We find that the failure to include asset prices in the aggregate price statistic has introduced a downward bias in the US Consumer Price Index on the order of magnitude of roughly ; percentage point annually. Of the three broad assets categories considered here – equities, bonds, and houses – we find that the failure to include housing prices resulted in the largest potential measurement error. This conclusion is also supported by a cursory look at some cross-country evidence.     

Testing Korteweg's rational expectations model for a small open economy

Summary Korteweg extended the Barro, Lucas, Sargent, Wallace type of rational expectations model to a small open economy. This paper tests Korteweg's model with Dutch data. A major error in the specification and estimation is pointed out and corrected: the differenced expected variables are not defined consistently. This error implies that Korteweg's and Bomhoff's previous empirical results on the model are invalid. The test results for the corrected model indicate that this model has to be rejected for The Netherlands. The restrictions implied by an extremely simple empirical alternative are, however, not rejected.I would like to thank Dr. Th.E. Nijman, Professors F. van der Ploeg, W.H. Buiter and J.J.M. Theeuwes and Dr. A. J. de Zeeuw for their stimulus and helpful comments on previous versions of this paper, and Professor P. Korteweg for his open-minded attitude towards this research.

On the scope of hydraulic macroeconomics: Some reflections on Alan Coddington's Keynesian Economics

Summary The questions which Alan Coddington's posthumous bookKeynesian Economics brings to the fore as well as the thought-provoking (rather than fully acceptable) answers it provides make it worthy of being taken up for further analysis and discussion. This review article is intended to be one possible contribution in this respect. It focuses on the way Coddington's book deals with subjectivist approaches in economics and criticises it for going astray in this respect by adopting a mistaken view on the proper method of economics and giving a mistaken interpretation of both Keynesian economics and the economics of Keynes.I am indebted to L. H. Hoogduin, I. M. Kirzner, J. A. Kregel, S. K. Kuipers, J.A.H. Maks, J. Muysken and J. Pen for their valuable comments and discussion on an earlier version of this paper. Of course, they cannot be blamed for any remaining errors.A. Coddington,Keynesian Economics: The Search for First Principles, George Allen and Unwin, London, etc., 1983. Pp. 129. £ 9.95     

Interpretation of error covariances with nonrandom data: An empirical illustration of returns to college education

Conclusion This paper reviews two models of selectivity and gives an interpretation of the covariance terms that are particular to self-selectivity models. While the second model examined in this paper has been discussed elsewhere, the estimates presented for the first model have not been discussed in previous papers. More importantly though, the paper proposes an hypothesis about the expected relationship between error covariances. According to this hypothesis, if all individuals who are faced with the choice between two regimes (1 and 2) choose the regime which yields a maximum value, then the expected relationship between covariances is ₁ < ₂ . If all individuals choose that regime which yields a minimum value, then the expected relationship between covariances is ₁ > ₂ . This relationship holds for a very general class of selectivity models, so long as individuals are choosing between regimes by comparing the expected value (to them) of each regime.This paper was written while I was working under the professional development program at CNA.
