The relationship between neighborhood physical environment and social disorder, particularly crime, is of critical interest to urban economists and sociologists, as well as local governments. Over the past 50 years, various policy interventions to improve physical conditions in distressed...

This paper addresses two basic issues related to technological innovation and climate stabilisation objectives: i) Can innovation policies be effective in stabilising greenhouse gas concentrations? ii) To what extent can innovation policies complement carbon pricing (taxes or permit trading) and...

We examine the effect of immigration on public spending from a theoretical (political economic) and an empirical perspective. We distinguish between public spending on private goods and on public goods. Our model implies that whether immigration increases or decreases public spending primarily...

Benefit incidence analysis is an extremely popular tool to assess the distribution of benefits from government expenditure in developing countries, particularly in the social sectors. The analysis describes the welfare impact of public spending on groups of people or households, typically along...

This survey examines the history and current practice in integrated assessment models (IAMs) of the economics of climate change. It begins with a review of the emerging problem of climate change. The next section provides a brief sketch of the rise of IAMs in the 1970s and beyond. The subsequent...

This paper uses a simple model to analyze the forces that determine the size of the public sector and the quality of workers employed in that sector. Workers are heterogeneous, and the public sector chooses an employment strategy that maximizes a social welfare function U(s, Y) that depends on...

Many areas of the natural and social sciences involve complex systems that link together multiple sectors. Integrated assessment models (IAMs) are approaches that integrate knowledge from two or more domains into a single framework, and these are particularly important for climate change. One of...
