This paper describes the development of population health and disability insurance utilization for older workers in Sweden and analyzes the relation between the two. We use three different measures of population health: (1) the mortality rate (measured between 1950 and 2009); (2) the prevalence...

This paper examines the evidence on the relationship between credit spreads and economic activity. Using an extensive data set of prices of outstanding corporate bonds trading in the secondary market, we construct a credit spread index that is--compared with the standard default-risk...

We present and experimentally test a mechanism that provides a simple, natural, low cost, and realistic solution to the problem of compliance with socially determined efficient actions, such as contributing to a public good. We note that small self-governing organizations often place enforcement...

Corporate credit spreads are large, volatile, countercyclical, and significantly larger than expected losses, but existing macroeconomic models with financial frictions fail to reproduce these patterns, because they imply small and constant aggregate risk premia. Building on the idea that...

We study the role of legal investor protection for the efficiency of the market for corporate control. Stronger legal investor protection limits the ease with which an acquirer, once in control, can extract private benefits at the expense of non-controlling investors. This, in turn, increases...

We use a combination of administrative and survey data to estimate the fraction of individuals newly enrolled in public health coverage (Wisconsin's combined Medicaid and CHIP program) that had access to private, employer-sponsored health insurance at the time of their enrollment and the...

This paper seeks to explain the key two stylized facts of fundamental reforms to social security systems worldwide: Why have so many countries reformed when traditional systems seem, at first glance, to have a higher probability of delivering a secure retirement income? Why have these reforms...

We address the question of the prediction of large failures, busts, or system collapse, and the necessary concepts related to risk quantification, minimization and management. Answering this question requires a new approach since predictions using standard financial techniques and statistical...

Why cooperation occurs when noncooperation appears to be individually rational has been an issue in economics for at least a half century. In the 1960's and 1970's the context was cooperation in the prisoner's dilemma game; in the 1980's concern shifted to voluntary provision of public goods; in...
