Recent developments in investment research have highlighted the importance of non-convexities and irreversibilities in the firms' adjustment of quasi-fixed inputs. However, aggregation across capital goods may smooth out the discontinuities associated with the adjustment of individual assets....

In this paper we study the determinants of investment decisions at the firm level with heterogeneous capital goods. We exploit a newly developed panel dataset of small and medium-sized firms which allows us to distinguish between purchases, sales, and net acquisitions of capital goods. We...

We construct measures of the annual cost of single-family housing for 46 metropolitan areas in the United States over the last 25 years and compare them with local rents and incomes as a way of judging the level of housing prices. Conventional metrics like the growth rate of house prices, the...

We analyse the dynamics of firms' employment decisions which underlie lumpy and kinked adjustment costs. We consider a dynamic structural model in which, in each period, firms face a choice of whether to vary the labour input or to postpone the adjustment to the future. By exploiting the first...

We analyse the conditions under which an (S,s) rule may be derived and compare these with alternative rules. We consider the case of labour demand with fixed adjustment costs. The (S,s) rule implies a specific ordering of choices: downward adjustment, non-adjustment and upward adjustment with...

In this paper we analyse methods which allow us to estimate and identify the sources of censoring in dynamic models. We explicitly take into account the existence of corner solutions by considering a discrete-time-discrete-choice dynamic structural model. The availability of microeconomic...

The purpose of this paper is to develop a model that integrates inventory and labor decisions We extend a model of inventory behavior to include a detailed specification of the role of labor input in the production process and of the costs associated with it In particular we distinguish between...

We analyze the relationship between the prices of ethanol, agricultural commodities and livestock in Nebraska, the U.S. second largest ethanol producer. The paper focuses on long-run relations and Granger causality linkages between ethanol and the other commodities. The analysis takes possible...

This paper examines the relationship between biofuels and commodity food prices in the U.S. from a new perspective. While a large body of literature has tried to explain the linkages between sample means and volatilities associated with ethanol and agricultural price returns, little is known...

This paper focuses on the results of the research work carried out by Fondazione Eni Enrico Mattei (FEEM) within the WISE project. This project aims at investigating the effects and the impacts of extreme weather events, particularly very warm summers, mild winters and storms, on the...
