State mandated benefits and the small firm's decision to offer insurance

In the last decade, the number of Americans without health insurance has grown, partly due to an erosion in employer-based coverage among workers. This paper examines the extent to which state-mandated benefit requirements and other state insurance regulations discourage small firms in the private sector from providing health benefits. Using data on 1320 firms observed in 1985 and 492 firms observed in 1988, we estimate two models of small firms' decisions to offer health insurance (one for each data set), and then use them to assess the effects that mandates had on purchasing decisions in both years. We estimate that 19 percent of noncoverage among sample businesses in 1985 and 43 percent of noncoverage in the 1988 sample was attributable to state-mandated benefits. State continuation-of-coverage requirements were particularly burdensome for firms. With continued growth in the number of state mandated benefit requirements, we should expect a steady rise in the small firm's propensity to forgo insurance coverage.     

Bayesian and consistent assessments

In a Bayesian assessment, beliefs are computed from the strategy profile applying Bayes rule at positive probability information sets. A consistent assessment is the limit point of a sequence of completely mixed Bayesian assessments. We characterize the set of extensive forms for which the sets of Bayesian and consistent assessments coincide. As an illustration of the results, we characterize consistency in some multi-period games with simultaneous actions.

Evaluation designs for technology assessments and forecasts

The worth of technology assessments and technological forecasts need not remain a matter of faith; indeed, it cannot. Evaluation of technology assessments and forecasts is indicated both to assess their effectiveness and to provide feedback useful for improving the state of the art. Drawing upon evaluation research, we present a range of alternative evaluation designs that fit into four general categories; pre-planned or post-hoc evaluations of single studies; pre-planned or post-hoc comparisons among multiple studies. We distinguish among three classes of performance objectives meriting evaluative attention: validity, utility, and advancement of the methodological art. For each objective we in turn consider pros and cons of several specific evaluation designs. We conclude with recommendations for two coordinated, but selective, evaluation programs, one focused on comparison among extrapolative forecasting techniques and one devoted to certain aspects of technology assessment methods and utilization.     

Employee benefits annual checkup

An annual checkup is a prudent preventive measure for employee benefit plans. It allows plan fiduciaries to assess the overall "health" of the plans they administer and to make proactive corrections. This article lists some of the most important items to consider in evaluating a plan.     

Intertemporal pricing in laboratory posted offer markets with differential information

Summary. This paper analyzes intertemporal seller pricing and buyer purchasing behavior in a laboratory retail market with differential information. A seller posts one price each period that a buyer either accepts or rejects. Trade occurs over a sequence of "market periods" with a random termination date. The buyer and seller are differentially informed: The seller's cost of producing a unit of a fictitious good is known and constant in all periods, but the buyer's value for the good (demand) is a random variable governed by a Markov Process whose structure is common knowledge. At the beginning of each period the unit's value is determined by "nature" and is privately revealed only to the buyer. The market termination rule is a binary random variable. We conduct 32 laboratory experiments designed to study intertemporal pricing by human subjects in the Posted Offer Institution when demand follows a stochastic process. There are four series of experiments: 8 with simulated buyers, 8 with inexperienced subjects, 8 with once experienced subjects, and 8 with twice experienced subjects.     

A study on Spanish female labour supply with job offer restrictions

This paper analyses female working time taking into account restrictions on hours. Moreover, we compare two different specifications of employment opportunities. The first one assumes that the probabilities of receiving different job offers are constant whereas in the second one we incorporate the hypothesis that these probabilities depend on individual characteristics. The model is estimated using a sample of Spanish women from the Encuesta Piloto sobre Ganancias y Subempleo (1990). The results suggest that incorporating job restrictions is a valuable extension and that individual variables affect the availability of job offers.JEL Classification: J22This paper is based on the second chapter of my Ph.

Societal benefits of illiquid bonds

In this paper, I provide a possible explanation of why nominally risk-free bonds are essential in monetary economies. I argue that the role of nominal bonds is to enable agents to engage in intertemporal exchanges of money. I show that bonds can only serve this role if they are illiquid (costly to exchange for goods). Finally, I argue that in economies in which nominal bonds are essential, it is optimal for monetary policy to respond to changes in the distribution of liquidity needs.
