Aggregate Land Rents, Expenditure on Public Goods, and Optimal City Size

Land Rents

We study the technological pre-conditions for competitive equilibrium in a multisectoral economy where“land” is an essential imput. Earlier results by Bidard and Salvadori require either very low interest rates or are unable to predict the type of final demand vectors that can be supported by an equilibrium. We extend these earlier results and show that a given level and structure of final dema...

Aggregate Demand and Expenditure

Consumption Expenditure Of the four components of aggregate demand, consumption expenditure C is the largest contributing to between 60% and 70% of total expenditure. For this reason, we often start our analysis with this particular component. This category of expenditure includes private spending on durable goods (automobiles, electronic goods, appliances, ... ), non-durable goods (food, cloth...

Optimal Public Expenditure with Inefficient Unemployment

This paper proposes a theory of optimal public expenditure when unemployment is inefficient. The theory is based on a matching model. Optimal public expenditure deviates from the Samuelson rule to reduce the unemployment gap (the gap between the current and efficient rates of unemployment). Such optimal “stimulus spending” is described by a formula expressed with estimable sufficient statistics...

Coalition formation with local public goods and group-size effect

Many public goods that are provided by coalitions have a group-size e¤ect. Namely, people prefer to consume a public good in a larger coalition. This paper studies local public goods games with anonymous and separable group-size e¤ect. The core is nonempty when coalition feasible sets are monotonic and players’preferences over public goods satisfy a condition called cardinal connectedness. More...
