As is known from the economic literature, the notion of negative/positive duration dependence defined in terms of a decreasing/increasing hazard function can solely be used as a basis for revealing whether negative/positive duration dependence is present or not. However, when concern is directed...

We investigate how transitions from unemployment are affected by economic incentives and spell duration. Based on unique Norwegian register data that exhibit the rarity of random-assignment-like variation in economic incentives, the causal parameters are identified without reliance on...

This paper summarizes assumptions made and results obtained in parts of the literature on welfare and sustainability accounting. I consider five di®erent assumptions that can be imposed independently of each other, producing 32 different combinations. This taxonomy is used to organize results...

According to recent literature on monetary policy, there are two different interpretations of inflation targeting; (1) an instrument rule that responds to a measure of inflation (forecast) deviations from target and (2) a discretionary optimizing strategy towards minimizing the inflation...

The purpose of screening programs is to discover at an early point in time serious diseases, such as cervical cancer and colorectal cancer, that can be treated at lower social costs than would be the case if detected at later stages of disease development. In general, three questions are at the...

We show within three technological environments that any efficient and non-decreasing allocation can be the unique optimum according to undiscounted utilitarianism for some choice of utility function. – Utilitarianism ; Intergenerational justice

What is the income of each sector of an economy? E.g., in the case of a country endowed with petroleum resources, what is the income of its petroleum sector? Here we present a definition of sectoral income, which is compatible with an important line of theoretical literature on comprehensive...

This paper reviews the literature on the effects of low steady-state inflation on wage formation, focusing on four different effects. First, under low inflation, downward nominal wage rigidity (DNWR) may prevent real wage cuts that would have happened had inflation been higher. Second, wages...

Parametric aggregation of heterogeneous micro production technologies is discussed. A four-factor Cobb-Douglas function with normally distributed firm specific coefficients and with log-normal inputs (which agrees well with the available data) is speciffied. Since, if the number of micro units...

Regulating an export firm (or a homogeneous industry) with private information about emission technology is analysed, when the firm, owned partly by foreigners, has an option to bypass domestic regulation through costly relocation. If the firm chooses to relocate, it will set up a new plant in a...
