Futures margin setting is important for an exchange policy since it is the balance between the loss and benefit of an exchange. This paper develops a method for setting the margin level for two-commodity portfolios. The bivariate extreme value theory is applied in our estimation to compute the...

This paper was commissioned by the APEC Working Group on Fisheries to examine the economic impact of eliminating tariffs on fish and fish products in APEC economies. Chapter II provides a qualitative assessment of the impacts of liberalization of fisheries trade drawing on the available data and...

We show how non-parametric flexibility can be attained in a structural labour supply model that can be used to analyse all sorts of (non-linear) tax and benefits reforms. The direct utility function is approximated with a series expansion. For given length of the expansion, the model is...

The thesis covers three topics on the labour market and on consumer demand. Chapters two and three focus on the labour market mobility and wage differentials between the formal sector and the informal sector in urban Mexico. Dynamic random effects panel data models are used in the analysis....

We analyze Engel curves for nuclear households in rural China. The sample includes more than 5000 nuclear families covering nineteen out of thirty Chinese provinces. We consider expenditures on food, also subdivided into several food subcategories such as cereals, or meat and fish, and other...

Nonparametric techniques are usually seen as a statistic device for data description and exploration, and not as a tool for estimating models with a richer economic structure, which are often required for policy analysis.This paper presents an example where nonparametric flexibility can be...

This paper investigates labour supply of the wives of the heads of households in Mexico City, with a focus on the impact of family structure. A static neoclassical structural model is used. We assume that each woman chooses her labour supply and corresponding income so that her utility is...

We analyze mobility in urban Mexico between three labor market states: working in the formal sector, working in the informal sector, and not working. We use a dynamic multinomial logit panel data model with random effects, explaining the labor market state of each individual during each time...

In this paper, we introduce the symmetric strong vector quasi-equilibrium problem. We then demonstrate that the symmetric strong vector quasi-equilibrium problem is solvable under the suitable assumptions. As an application, we get an existence theorem of the strong saddle points of...
