A model of adjuncts in higher education

We examine the phenomenon of the expanded use of non-tenure-track positions (“adjuncts”) and construct a supply-side Harris–Todaro model. Low adjunct wages are attributable to a “Hope Rent” from the gap between private opportunities and tenure-track utility.     

Redistribution and employment policies with endogenous unemployment

We study optimal redistribution policy in an economy with three types of unemployed persons: those unable to work, the voluntarily unemployed, and the involuntarily unemployed. Both voluntary and involuntary unemployment are endogenous. Voluntary unemployment arises because individuals have different preferences, while involuntary unemployment results from frictions in the labour market or from an efficiency wage. We consider the employment policies of a well-informed government when it can and cannot commit to its policies. The model is simple, yet rich enough to reflect real-world policies, including transfers to the disabled, welfare for non-working employables, unemployment insurance, employment subsidies, and taxes on workers and firms.     

The beneficial effects of generous unemployment benefits on profits and employment

Theories of the labor market generally predict that high unemployment benefits put upward pressure on wages, thus diminishing the profitability of employing labor and exacerbating unemployment. It remains to be explained why firms agree to contribute to generous schemes (replacement rates for general schemes in Europe and US are in the range 50–85%) that they are often willing to supplement (with sector- or firm-specific schemes that may involve even 100% replacement and long benefit duration). An answer can be found by including in the shirking–efficiency wage model, the hypotheses that workers are risk-averse and that those discharged for misconduct are not eligible to benefits. It is then optimal for risk-neutral firms (and for employment) to introduce an insurance scheme with full income coverage and with a duration limited only by the workers' participation constraint (there is no trade-off between level and duration of benefits). The more difficult it is to detect and fire shirkers, the higher is the rent workers enjoy above the competitive wage and the longer is the benefit duration consistent with the participation constraint. This result can be interpreted as a complementarity between the strictness of employment protection legislation (EPL) and the duration of benefits, which seems to conform with broad patterns observed in primary vs. secondary employment and in continental Europe vs. Anglo-Saxon countries.     

Finance and unemployment: new panel evidence

The effect of credit market imperfections on unemployment is largely investigated in the context of financial crises. This paper shifts the focus toward financial development and structure in a panel of advanced and developing countries. Some important findings emerge. Unemployment increases with financial development and concentration in banking markets but decreases with market orientation, the effect is stronger in magnitudes for young workers than female ones. More rigid market regulation increases unemployment. These findings are particularly pronounced for countries with higher income, better developed financial sectors, lower income inequality, greater trade openness, higher democracy, and common-law systems.     

Renewable energy and unemployment: A general equilibrium analysis

Using a three-sector general equilibrium model, the impact of renewable electricity support policies on the rate of equilibrium unemployment is analyzed. In a simple two-factor version of the model, the paper shows analytically that renewable electricity support policies lead to an increase in the rate of unemployment. A numerical analysis is conducted with an expanded three-factor model. In this version, most scenarios analyzed also lead to an increase in equilibrium unemployment. However, the paper identifies conditions in which renewable energy support policies can decrease the rate of equilibrium unemployment. In particular, when the elasticity of substitution between capital and labor is low, when capital is not mobile internationally, and when the labor intensity of renewable generation is high relative to conventional generation, renewable electricity support policies may reduce the rate of equilibrium unemployment. The model is parameterized to represent the US economy, such that the magnitudes of quantities can be observed. Although there is some variation in the results depending on parameters, the findings suggest in general that reducing electricity sector emissions by 10% through renewable electricity support policies is likely to increase the equilibrium unemployment rate by about 0.1–0.3 percentage points.     

Classical and Keynesian unemployment in Austria

The labor market in a macroeconometric model of Austria is used to determine the natural unemployment rate, full-employment (F.E.) output, and the F.E. real wage for 1966–92. Gaps between actual and F.E. variables are examined analytically and historically. Observed unemployment is decomposed into natural, hidden, classical, and Keynesian components. Classical unemployment is associated with the real wage gap, while Keynesian unemployment depends on the output gap. A rise in the natural rate is found to account for almost all of the increase in unemployment between 1966–74 and 1975–81, but an increase in Keynesian unemployment is the major factor in the rise of unemployment between 1975–81 and 1982–92. A fiscal shock to the complete model is found to increase real GDP for a year or two, reducing Keynesian unemployment without an appreciable rise in classical unemployment; the wage gap is eventually increased, however, producing a modest rise in classical unemployment.A lengthier version of this paper was presented at the Annual Meeting of the Austrian Economic Association, Graz, April 14–16, 1993. The generous finacial support of the Jubiläumsfonds of the Austrian National Bank for the research of which this paper is a part is gratefully acknowledged.     

Long-term unemployment, the invention of 'hysteresis' and the misdiagnosis of structural unemployment in the UK

This paper investigates the empirical basis for the belief thatunemployment makes people less ‘employable’, andthat the existence of a pool of long-term unemployed peopleis therefore in itself a barrier to full employment. Drawingon data for Great Britain from the 1940s to the present day,it shows that this idea has arisen through misinterpretationsof the statistical evidence. The resulting policies, besidesdiverting resources from the demand-side programmes appropriateto the true situation of structural unemployment, appear tohave created a problem of the kind they were intended to address,by encouraging unemployed people to move onto sickness benefits.     

Inequality,unemployment, and endogenous growth in a political economy with a minimum wage

This paper presents development of an endogenous growth model with heterogeneous households and political determination of the minimum wage. We investigate the interaction of inequality, unemployment, and economic growth. First, the arguments in this paper show that a positive correlation exists between inequality and unemployment, Second, the interaction between inequality and economic growth is shown to be a positive relation if high inequality pertains in a society. It is a negative relation if low inequality pertains.      

Censored quantile regressions and the length of unemployment periods in West Germany

In this paper, we estimate the effect of different macro and micro variables on the distribution of unemployment duration in West Germany using censored quantile regressions. We analyze unemployment periods of more than 91,000 observations from the years 1981 to 1997 drawn from the IAB employment subsample. The latter is an administrative data set that is representative with respect to the socially insured workforce. Surprisingly, we find that the educational degree and variables indicating the macroeconomic environment such as the unemployment rate have a weak effect only. On the other hand, variables reflecting the (un-)employment history of an individual such as the length of tenure, recall to the same employer in the past, recent unemployment, and the position in the population income distribution before unemployment have the strongest effects on unemployment duration. We conclude that work history variables are the ones most suitable in characterizing the unemployment duration of an individual. From a methodological point of view, it is interesting that some regression coefficients have a different sign depending on the quantiles of the unemployment duration distribution. This clearly is a violation of the classical proportional hazard assumption which is very common in unemployment duration analysis.     

The relationship between entrepreneurship and unemployment: Is Portugal an outlier?

The present paper examines the relationship between entrepreneurship, as measured by the variation in business ownership rates, and unemployment in Portugal in the period from 1972 to 2002. It concludes that Portugal has been a relative outlier in regard to the effects of entrepreneurship on unemployment when compared with the OECD average. Although the nature of entrepreneurship may be different in the Portuguese case, due to a high proportion of “micro-businesses” created for subsistence which have little impact on growth and employment, this factor does not seem to be the primary reason for the observed discrepancies. The differences between observed levels of unemployment for Portugal and those predicted by a model based on OECD data seem to be mostly associated with macroeconomic fluctuations associated with European business cycles and EU “cohesion” funding, as well as with adjustment costs to new technology adoption which lead to productivity slowdowns, thus increasing the time lag for the effect of entrepreneurship on employment beyond the OECD average.     

Benefit entitlement and unemployment duration: The role of policy endogeneity

The potential duration of benefits is generally viewed as an important determinant of unemployment duration. This paper evaluates a unique policy change that prolonged entitlement to regular unemployment benefits from 30 weeks to a maximum of 209 weeks for elderly individuals in certain regions of Austria. In the evaluation, we explicitly account for the fact that the program was an endogenous policy response to deteriorating labor market conditions for older workers in certain regions and sectors. The main results are: (i) REBP reduced the transition rate to jobs by 17%; (ii) accounting for endogenous policy adoption is important and quantitatively significant.     

Regional and gender differentials in the persistence of unemployment in Europe

The persistence of unemployment increased during the recent great recession in many European countries, although with diversified impacts. We therefore analyse such impacts in four European countries – Italy, Spain, France and the UK – which represent different institutional frameworks and may reflect the so-called continental European and Anglo-Saxon frameworks. We analyse the determinants of unemployment persistence using individual-level data from the European Union Statistics on Income and Living Conditions (EU-SILC) panel for the period 2007–2013. These data enable us to take into account initial conditions and state dependence in addition to individual and household characteristics. We focus on gender and regional effects, which have a strong impact on the persistence in the state of unemployment. We find that gender gap is significant in Italy and the UK, implying that male workers show a higher probability of remaining unemployed. In Italy, such a pattern is due to the worsening of male workers’ conditions during the crisis, whereas in the UK, male workers show higher unemployment rates than women. Regional effects are significant in all countries analysed and underline a relevant structural factor that should be addressed on policy grounds in Europe. Such effects are greater in Spain and Italy.

Tariffs,trade and unemployment in a disequilibrium model: issues and policies

This paper studies the disequilibrium transition process engaged by increased openness to trade, and the effect of institutions, market behaviors and economic policies on that transition. The issue is analyzed with a simple two country (north and south), two goods model, amended in order to take into account the time dimension of both the production and the decision processes. Investigating the consequences of a tariff decrease by means of numerical simulations, we show to what extent wage and price setting, and the degree of tightness of monetary policy affect the outcome of the disequilibrium process. The main result is that capturing the gains associated with international trade requires market behaviors and economic policies, which are rather different from what is usually prescribed.

Worker flows, job flows and unemployment in a matching model

Standard matching models of unemployment generate far too little volatility in unemployment and vacancies relative to the variation in the shock variables. Shimer (2005) showed that in US data the vacancy-to-unemployment ratio is about 26 times more volatile than the standard model predicts. He identified the flexibility of wages as the key issue and triggered a heated debate on possible improvements of the core model to accommodate these empirical facts. In this paper, we first document Shimer's facts for the UK and find them to be qualitatively similar to US facts. We then develop and calibrate a model based on the Mortensen and Pissarides approach that increases the volatility of the v/u ratio 20-fold compared to the standard framework. The key features of our model relate to the job creation decision by firms and the search options of workers. We allow these to search whilst employed, and firms to re-advertise jobs that have been quit from. This leads us to use a different job creation process, whereby potential vacancies, or job ‘ideas’, arise at a finite rate per period over a range of idiosyncratic productivities. Calibrating the model to UK data, we show that it delivers volatility in unemployment and vacancies much closer to, though still not as large as, that observed for the UK, whilst retaining the standard wage determination process.     

On the links between unemployment rate, monetary creation and the value-added sharing

In this paper, we investigate the analytical links between the rate of unemployment, monetary creation and how individuals share the value added in an economy with three types of agents: capital owners, managers and employees. This relationship relies on the fact that the rate of unemployment depends on many macroeconomic characteristics such as: creation of money, external balance of goods and services and mark-up pricing. The latter being decomposed into the expected margin rate and the growth rate of the unitary wage cost that characterize the primary value-added sharing.     

Patinkin,the Cowles Commission,and the theory of unemployment and aggregate supply

The paper provides an account of Don Patinkin's long-time search for an explanation of the notions of an aggregate demand constraint and unemployment under the assumption of a perfectly competitive goods market. It is argued that Patinkin's quest is reflected on the development of the concept of an aggregate supply function in the goods market. Patinkin's interpretation of aggregate supply and unemployment is compared to similar ideas put forward by Jacob Marschak, Trygve Haavelmo and Lawrence Klein, his former colleagues at the Cowles Commission in Chicago.     

Persistent unemployment and co-ordination issues: an evolutionary perspective

Abstract. In this paper we look at unemployment as a phenomenon which reflects the co-ordination problems that characterize out-of-equilibrium processes of adjustment. The analysis carried out shifts the focus from structural factors to the economic process. It shows that unemployment cannot be satisfactorily explained – and policy interventions devised – by focusing only on specific characters of the technology or confining the analysis to structural factors concerning the labour market. The co-ordination mechanisms of adjustment processes rather than the fundamentals of the economy appear, in this light, as the main determinants of differences in unemployment trends in different economies; and monetary policy comes back to the center of the stage as an essential element of the working of these mechanisms.

Canadian stock market multiples and their predictive content

A substantial variation in the Canadian E/P ratio can be explained by a combination of the lagged level of the E/P along with variability in logical explanatory factors. Moreover E/P ratios have a predictable component, both in the short-term and longer-term. On the other hand, short-term stock market returns are unpredictable. But, consistent with U.S. evidence, longer-term returns are predictable, especially when one conditions on the dividend yield.
