The Effects of Inflation and Taxes on Growth Investments and Replacement Policies

This paper investigates the effect of inflation and taxes on the optimal duration of investments. The main conclusion is that inflation does not always increase the duration of investments. For example, in the case of equipment with a short replacement cycle, increased inflation tends to decrease the duration of the cycle. Contrary to the common theoretical analysis, these results imply that inflation may increase some forms of capital investments.     

Worker Control and Workplace Learning: Expansion of the Job Demand-Control Model

This paper uses a sub-sample ( N  = 5,800) of a unique data set on work and lifelong learning to develop the learning dimension of the Job Demand-Control model ( Administrative Science Quarterly [1979] 24:285 ). The model is expanded by including three distinct learning behaviors to allow for a complete assessment of workplace learning. Worker control is also expanded to include often confounded dimensions of Social and Technical Control. The results confirm that different types of learning are related to different determinants and that Social and Technical Control are key factors in learning participation.     

Asset Bubbles and the Cost of Economic Fluctuations

Lucas (1987, 2003) estimates that the cost of economic fluctuations is low; a social planner would pay no more than 0.1% of (permanent) consumption to eliminate all future business cycle fluctuations. The current paper extends Lucas’ calculations by studying the costs of fluctuations arising from asset bubbles. We estimate two classes of costs: consumption volatility due to asset bubbles in a representative agent economy and consumption volatility that arises because households have heterogeneous exposure to the bubble assets. We show that the magnitude of welfare costs is primarily driven by the existence of heterogeneity. Our benchmark calibration implies that the asset bubbles of the last decade generated a social welfare cost equal to a permanent 3% reduction in the level of national consumption. If assets are held proportionately across the population, these welfare costs fall by an order of magnitude. Our calculations are sensitive to the details of the calibration, including the degree of balance sheet and trading heterogeneity, the coefficient of relative risk aversion, and the magnitude of the asset bubble. Our preferred specifications generate welfare costs ranging from 1% to 10% of (permanent) national consumption.     

The Economic Impact of the Boston Living Wage Ordinance*

This paper presents one of the first quantitative assessments of the effect living wage laws have had on firms covered by their mandate. Applying difference‐in‐difference estimation methods to survey data from Boston, Massachusetts, I find little evidence of reduced employment or hours worked, following living wage implementation. Instead, there is strong evidence that firms actually shifted from part‐time towards full‐time staffing as a result of Boston's living wage law. Estimates also reveal a substantial degree of wage compression within firms who raised wages. Finding no evidence of reduced employment or hours, this paper uses qualitative survey data to examine other ways in which firms may have adjusted to higher wages. I find some evidence that covered firms have taken lower profits as a way to adjust to the Boston law.     

PESSIMISM OR OPTIMISM: A JUSTIFICATION TO VOLUNTARY CONTRIBUTIONS TOWARD ENVIRONMENTAL QUALITY*

This article analyses the determinants of voluntary contribution to environmental quality by introducing the perception of environmental risk. We consider individuals who are aware both of the impact of their voluntary contributions and of the quality of the current environment on the future quality of environment. Their preferences are represented by the RDU model. We distinguish three kinds of effect: environmental quality, wealth and risk perception. The first effects are not always sufficient to explain agents' implication in the improvement of environmental quality.
