This paper attempts to reconcile the contradictory findings in the debate over school resources and school effectiveness by highlighting the role of aggregation in the presence of omitted variables bias. While data aggregation for well- specified linear models yields unbiased parameter...

This paper analyzes the effect of time aggregation on estimates of the elasticities of output with respect to employment and to average hours of work. The main goal is to get accurate estimates of production function parameters. Low frequency data generate better estimates of output- employment...

How is econometric analysis (of partial adjustment models) affected by the fact that, while data collection is done at regular, fixed intervals of time, economic decisions are made at random intervals of time? This paper addresses this question by modelling the economic decision making process...

We investigate the effects on saving and growth of the rent sharing between firm owners and workers documented in recent empirical work. In an overlapping-generations framework, more rent sharing is found to increase growth. This result also holds in a model with a single generation of...

In this paper we consider and illustrate a solution to the inter-related problems of monetary aggregation and estimation of money demand. The problem with the definition of money is that the relative prices of the monetary components fluctuate over time, rendering simple-sum aggregates...

This research examines the effect of spatial aggregation on the accuracy of regional economic forecasts. Literature in econometrics, business forecasting, regional economic forecasting, spatial econometrics, and spatial time series analysis suggests that the issue is far from settled at either...

Inferences about the effects of money on economic activity may depend importantly on the choice of a monetary index because simple-sum aggregates cannot internalize pure substitution effects. This hypothesis is investigated by replicating five recent studies that have challenged an aspect of the...

Compensation for natural resources damage may be provided, in principle, by a payment equal to the value of damage, a compensating restoration project, or partial restoration plus a compensating payment. Applicable laws have a pronounced tilt toward restoration. When determining the value of...

We test whether dynamic, stochastic, general equilibrium artificial economies associated with several labor market institutions provide an adequate characterization of aggregate employment volatility and dynamics. Our test is robust to possible misspecifications about the information set used by...
