In the last decade, a large body of literature has been developed to explain the universal features of inequality in terms of income and wealth. By now, it is established that the distributions of income and wealth in various economies show a number of statistical regularities. There are several models to explain such static features of inequality in an unifying framework and the kinetic exchan...

From an analysis of the long-run electric generating requirements of several representative utilities, it is concluded that the energy supplied by solar photovoltaic power devices will displace primarily base-load, and to a lesser extent intermediate, generating plants, even at relatively modest penetrations corresponding to several percent of the utility peak load. Attaching photovoltaic devic...

Following the initial shocks associated with the collapse of communism, and the probolems of implementing a broad range of market-oriented reforms, achieving sustained growth requires an economic environment favouring high rates of savings and investment, encouraging for foreign investors, and conducive to profitable, highly productive investment. This is especially hard in the transition econo...

We present evidence from randomized field experiments that 401(k) savings choices are significantly affected by one- to two-sentence anchoring, goal-setting, or savings threshold cues embedded in emails sent to employees about their 401(k) plan. Even though these cues contain little to no marginal information, cues that make high savings rates salient increased 401(k) contribution rates by up t...

Based on anecdotal evidence—both verbal and written—from nurses, they appreciate the value these services have on their personal and professional lives. On average, a single nurse will save as many as five hours per month by using a hospital’s concierge service. When that number is multiplied by an average of 500 requests per month placed by a hospital’s staff, a hospital can save its nurses as...

In this paper, I consider the problem of optimal unemployment insurance in a world in which the unemployed agent’s job-finding effort is unobservable and his level of savings is unobservable. I show that the first-order approach is not always valid for this problem, and I argue that the available recursive procedures are not currently computationally feasible. Nonetheless, for the case in which...

It has been suggested that rationalisation of health funds will generate significant albeit unquantified cost savings and thus hold or reduce health fund premiums. 2001-2 Private Health Industry Administration Council (PHIAC) data has been used to analyse these suggestions. Payments by funds for clinical services will not vary after fund rationalisation. The savings after rationalisation will a...

Better insurance against rainfall risk could improve the security of hundreds of millions of agricultural households around the world. This paper theoretically and experimentally analyzes an innovative financial product called a Weather Insurance Savings Account (WISA), which combines savings and rainfall insurance. We index the insurance share of the WISA by γ ∈ [0, 1] and use a standard model...

This paper develops a two-period-two-country model in which an altruistic donor faces Samaritan’s Dilemma to address two important policy questions: (i) whether foreign aid can lead to efficient level of capital investment in the recipient country and (ii) how do the form (e.g. budgetary transfers, capital transfer) and the timing of aid affect the incentives of the recipient? It finds that the...
