We present a static model of aggregate demand and unemployment. The economy has a nonproduced good, a produced good, and labor. Product and labor markets have matching frictions. A general equilibrium is a set of prices, market tightnesses, and quantities such that buyers and sellers optimize...

The aim of this paper is to survey the "hard" evidence on the effects of subjective well-being. In doing so, we complement the evidence on the determinants of well-being by showing that human well-being also affects outcomes of interest such as health, income, and social behaviour. Generally, we...

This paper explains the nonneutrality of money from two assumptions: (1) consumers dislike paying prices that exceed some fair markup on firms' marginal costs; and (2) consumers under infer marginal costs from available information. After an increase in money supply, consumers underappreciate...

Especially in developing countries credit constraints are often perceived as one of the most important market frictions constraining firm innovation and growth. Huge amounts of public money are being devoted to the removal of such constraints but their effectiveness is still subject to an...

In this paper we study the causal impact of police on crime by looking at what happened to crime before and after the terror attacks that hit central London in July 2005. The attacks resulted in a large redeployment of police officers to central London boroughs as compared to outer London - in...

In this paper we look at the relationship between crime and economic incentives in a different way to other workin this area. We look at changes in unemployment benefits and the imposition of benefit sanctions as a means ofstudying the way that people on the margins of crime may react to...

Do other peoples' incomes reduce the happiness which people in advanced countries experience from any given income? And does this help to explain why in the U.S., Germany and some other advanced countries, happiness has been constant for many decades? The answer to both questions is 'Yes'. We...

In normative public economics it is crucial to know how fast the marginal utility of income declines as income increases. One needs this parameter for cost-benefit analysis, for optimal taxation and for the (Atkinson) measurement of inequality. We estimate this parameter using four large...

In this paper we look at links between police resources and crime in a different way to the existing economics of crime work. To do so we focus on a policy intervention - the Street Crime Initiative - that was introduced in England and Wales in 2002. This allocated additional resources to some...

A rise in population caused by increased immigration, is sometimes accompanied by concerns that the increase in population puts additional or differential pressure on welfare services which might affect the net fiscal contribution of immigrants. The UK and Germany have experienced significant...
