Wage Inequality and the Changing Organization of Work.
This paper sheds light on how changes in the organization of work lead to wage inequality. We present a theoretical model in which workers with a wider span of competence (higher level of multitasking) earn a wage premium. Since abilities and opportunities to expand the span of competence are distributed unequally among workers across and within education groups, our theory explains (1) rising wage inequality between groups, (2) rising wage inequality within groups, and (3) the polarization of work and the decoupling of the income distribution. Using a rich German data set covering a 20-year period from 1986 to 2006, we provide empirical support for our model.
Envy, Guilt, and the Phillips Curve
We incorporate inequity aversion into an otherwise standard New Keynesian dynamic equilibrium model with Calvo wage contracts and positive inflation. Workers with relatively low incomes experience envy, whereas those with relatively high incomes experience guilt. The former seek to raise their income, and latter seek to reduce it. The greater the inflation rate, the greater the degree of wage dispersion under Calvo wage contracts, and thus the greater the degree of envy and guilt experienced by the workers. Since the envy effect is stronger than the guilt effect, according to the available empirical evidence, a rise in the inflation rate leads workers to supply more labor over the contract period, generating a significant positive long-run relation between inflation and output (and employment), for low inflation rates. This Phillips curve relation, together with an inefficient zero-inflation steady state, provides a rationale for a positive long-run inflation rate. Given standard calibrations, optimal monetary policy is associated with a long-run inflation rate around 2 percent.inflation, long-run Phillips curve, fairness, inequity aversion
Challenges to social cohesion and approaches to policy reform.
Now, at the end of the 20th century, many OECD countries face serious problems in achieving both prosperity and social cohesion. One important - and sadly neglected - source of these problems are the very policy systems that are meant to address them. I will argue that these policy systems - including taxes and transfers, regulations governing employment, welfare services, and many more - are imparting a serious long-term imbalance to their host countries, by making these countries increasingly vulnerable to economic, social and political shocks. Although these policy systems were originally designed with the express aim to cushion citizens from these shocks and to provide security against a variety of uncertainties, their long-term effect is turning out to be the opposite of what was intended. This paper examines how and why this has happened and then turns to some important, recent economic developments that are likely to make this problem more serious in the future. Finally, it examines a strategy for economic policy reform that addresses the problem and thereby provides a means for achieving more favorable economic and social outcomes in the years ahead.Sozialer Wandel; Wirtschaftskrise; Wirtschaftspolitik; OECD-Staaten;
Hyperbolic Discounting and Positive Optimal Inflation
The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic discounting, small positive rates of inflation can be optimal. In our baseline calibration, the optimal rate of inflation is 2.1% and remains positive across a wide range of calibrations.optimal monetary policy, inflation targeting, unemployment, Phillips curve, nominal inertia, monetary policy
The Division of Labor and the Market for Organizations
The paper examines the determinants of the division of labor within firms. It provides an explanation of the pervasive observed changes in work organization away from the traditional functional departments and towards multi-tasking and job rotation. Whereas the existing literature on the division of labor within firms emphasizes the returns from specialization and the need for coordination of the work of different workers, the present analysis focuses on the returns from multi-tasking, which is shown to arise from informational and technological complementarities among tasks as well as from the exploitation of the versatility of human capital. The paper also explores how the move towards multi-tasking can affect the labor market, and the distribution of firms across organizational forms.Division of labor, specialization, multi-tasking, organization of work, technological change, information flows
The Firm as a Pool of Factor Complementarities
This paper presents a new approach to the theory of the firm by identifying factor complementarities as central to the determination of the firm’s boundaries. The factor complementarities may take a variety of forms: technological and informational complementarities, as well as economies of scale and scope. We examine the tradeoff between the gains from these complementarities and transactions costs. In so doing, we must abandon the standard dichotomy between the determinants of plant size and firm size. The influence of factor complementarities on firm size is examined in partial and general equilibrium frameworks.
Inflation Persistence and the Phillips Curve Revisited
A major criticism against staggered nominal contracts is that they give rise to the so called "persistency puzzle" - although they generate price inertia, they cannot account for the stylised fact of inflation persistence. It is thus commonly asserted that, in the context of the new Phillips curve (NPC), inflation is a jump variable. We argue that this "persistency puzzle" is highly misleading, relying on the exogeneity of the forcing variable (e.g. output gap, marginal costs, unemployment rate) and the assumption of a zero discount rate. We show that when the discount rate is positive in a general equilibrium setting (in which real variables not only affect inflation, but are also influenced by it), standard wage-price staggering models can generate both substantial inflation persistence and a nonzero inflation-unemployment tradeoff in the long-run. This is due to frictional growth, a phenomenon that captures the interplay of nominal staggering and permanent monetary changes. We also show that the cumulative amount of inflation undershooting is associated with a downward-sloping NPC in the long-run.Inflation dynamics, Persistence, Wage-price staggering, New Phillips curve, Monetary policy, Frictional growth

Envy, guilt, and the Phillips curve
We incorporate inequity aversion into an otherwise standard New Keynesian dynamic equilibrium model with Calvo wage contracts and positive inflation. Workers with relatively low incomes experience envy, whereas those with relatively high incomes experience guilt. The former seek to raise their income, and the latter seek to reduce it. The greater the inflation rate, the greater the degree of wage dispersion under Calvo wage contracts, and thus the greater the degree of envy and guilt experienced by the workers. Since the envy effect is stronger than the guilt effect, according to the available empirical evidence, a rise in the inflation rate leads workers to supply more labor over the contract period, generating a significant positive long-run relation between inflation and output (and employment), for low inflation rates. This Phillips curve relation, together with an inefficient zero-inflation steady state, provides a rationale for a positive long-run inflation rate. Given standard calibrations, optimal monetary policy is associated with a long-run inflation rate around 2 percent. --inflation,long-run Phillips curve,fairness,inequity aversion
