A multi-regional general equilibrium model to assess policy effects at regional level AgEcon
Lovo, Stefania; Magnani, Riccardo; Perali, Carlo Federico.
In this paper we develop a multi-regional general equilibrium model (MEG-R) to compare the social desirability of the CAP reform in the three Italian macro-regions: North, Center and South. The model employs a mixed complementary framework that allows for the decision of not producing a particular crop in one or more regions and presents an attempt to model interregional trade flows. The model incorporates the links between production and consumption that characterize farm household’s behavior and allows for heterogeneous household responses across regions. Results show a general tendency to reallocations from cereal crops to forage that appear more severe in the South. In this region, the reduction in crops cannot be translated into an effective expansion...

EXPLORING ALTERNATIVES FOR ESTIMATING SYSTEMS OF EQUATIONS WITH MULTIPLE CENSORED VARIABLES: FARM OUTPUT SUPPLY AND INPUT DEMAND AgEcon
Arias, Carlos; Perali, Carlo Federico.
This paper explores two alternatives for estimating systems of equations with multiple censored variables: Maximum Simulated Likelihood and a two-step technique that seems to be well suited for large samples. The empirical part of the paper estimates a system of cost, cost shares and revenue shares equations of Italian farms using both approaches.

ISSUES IN DATA MANAGEMENT OF EXPENDITURE SURVEYS: AN EXAMPLE FROM THE COLOMBIAN 1984-85 URBAN SURVEY AgEcon
Perali, Carlo Federico; Cox, Thomas L..
This study examines some of the issues that are often encountered when analysing the socio-economic information of expenditure surveys using the Colombian 1985 urban expenditure survey as an example. This study discusses the problem of estimating prices when only information on expenditures and demographic characteristics is available, the options available when aggregating commodities and defining demographic or labour information, and the advantages and drawbacks in choosing total expenditure as a proxy for income or as the metric for poverty measurement. The study also applies non-parametric density estimation as a form of exploratory data analysis and as a means to learn from the data about the most proper parametric specification.

New Results On Censored Regression with Applications to Transactions Costs, Household Decisions and Food Purchases AgEcon
Holloway, Garth J.; Mazzocchi, Mario; Perali, Carlo Federico.
We generalize the Tobit censored regression to permit unique unobserved censoring thresholds conditioned by covariates and a set of common response coefficients. This situation , we argue, is one arising frequently in applications of censored regression and we provide three diverse examples to motivate the theory. We derive a robust estimation algorithm with three noteworthy features. First, by augmenting the observed-data likelihood with the censored observations, the estimation strategy is the same as Chib (1992) who derives Bayes estimates of the conventional censored regression. Second, by virtue of its generality, the model is applicable to a much broader set of circumstances than the conventional Tobit regression, which is nested as a special case of...

Primal-Dual Estimation of a Linear Expenditure Demand System AgEcon
Paris, Quirino; Perali, Carlo Federico; Piccoli, Luca.
Efficient estimates require the utilization of all the available theoretical and statistical information. This fact suggests that econometric models based on an explicit optimization theory might achieve more efficient estimates when all the primal and dual relations are used for a joint estimation of the model’s parameters. We present a discussion of this idea using a Linear Expenditure System (LES) of consumer demand. We assume that the risk-neutral household chooses its consumption plan on the basis of expected information. Some time after that decision, the econometrician attempts to measure quantities and prices and in so doing commits measurement errors. Hence, the econometric model is an errors-in-variables nonlinear system of equations for which...

Simulating the Impact on the Local Economy of Alternative Management Scenarios for Natural Areas AgEcon
de Agostini, Paola; Lovo, Stefania; Pecci, Francesco; Perali, Carlo Federico; Baggio, Michele.
This working paper estimates the impact on the local economy of the High Garda Natural Park of alternative management scenarios for the West Garda Regional Forest. The local economy is specialized in tourist services and strongly linked to the tourist presence and their level of expenditure. We wish to investigate the effects of the participative management strategy, which takes into account users preferences and the non-participative strategy, using the SAM multiplier analysis. The local SAM has been constructed considering three sectors: agriculture, tourism and a third aggregate sector including all the other activities. The resident population has been divided into two categories: residents employed in the tourist sector and the remaining resident...

The Collective Household Enterprise Model: An Empirical Analysis AgEcon
Menon, Martina; Perali, Carlo Federico.
This paper estimates a household model where both the production and consumption sides are observed. The household activities produce both marketable and nonmarketable products. Family members consume market goods, domestically produced goods and leisure. This household equilibrium model is described within a collective framework. The data are from a nation-wide sample of Italian farm-households. The estimation is implemented using a generalized Heckman estimator to account for corner solutions generated by the fact that not all households are engaged in all enterpreneurial activities and do not consume some of all goods and leisure. The identification of the sharing rule stems from the assignability of clothing consumption and leisure.

THE DEMAND FOR FLUID MILK PRODUCTS IN THE U.S.: A DEMAND SYSTEMS APPROACH AgEcon
Gould, Brian W.; Cox, Thomas L.; Perali, Carlo Federico.
The demand for fluid milk products has changed dramatically in recent years not only in terms of lower levels consumed but also in terms of the composition of the products consumed. A time-series based demand system analysis of the market for lowfat and whole milk products is developed incorporating the effects of changes in prices and demographic characteristics. From the estimated model, the impacts of future changes in the demographic profile of the U.S. population on fluid milk demand are analyzed.
