The serological cross-reactivity between lipopolysaccharides (LPS) of S. fidelis KMM3582(T) and rabbit anti-O P. mirabilis antibodies was tested. Using ELISA and Western blot cross-reactivity between S. fidelis LPS and antisera against P. mirabilis O14, O3 LPSs was found. The observed cross-reaction may suggest that anti-P. mirabilis S1959 (O3) antibodies may bind to the internal part of S. fid...

In this paper we deal with the utility maximization problem with a general utility function. We derive a new approach in which we reduce the utility maximization problem with general utility to the study of a fully-coupled Forward-Backward Stochastic Differential Equation (FBSDE).

This paper considers a neoclassical optimal growth problem where the shock that perturbs the economy in each time period is potentially unbounded on the state space. Sufficient conditions for existence, uniqueness and stability of equilibria are derived in terms of the primitives of the model using recent techniques from the field of perturbed dynamical systems.

This paper studies fitted value iteration for continuous state numerical dynamic programming using nonexpansive function approximators. A number of approximation schemes are discussed. The main contribution is to provide error bounds for approximate optimal policies generated by the value iteration algorithm. Journal of Economic Literature Classifications: C61, C63

The paper proposes an Euler equation technique for analyzing the stability of differentiable stochastic programs. The main innovation is to use marginal reward directly as a Foster–Lyapunov function. This allows us to extend known stability results for stochastic optimal growth models, both weakening hypotheses and strengthening conclusions. JEL classification: C61; C62; O41

Partially specified probabilities induce coherent risk measures of a special kind. These measures are axiomatized using the four axioms that characterize coherent risk measures and an additional one, which requires that the risk measure be additive on the set of efficient portfolios.

Household diversification into nonfarm work activities is a major rural livelihood strategy in many developing economies. In this paper, we explore empirically if rural households in Uganda leverage their nonfarm earnings to overcome credit constraints and invest in high yielding maize seed varieties. We use a semiparametric estimator of binary outcomes that accommodates endogenous regressors s...

In this paper we search for pollution haven consistent evidence within China. Using a province level data set and three different measures of environmental stringency, we investigate whether inward foreign direct investment (FDI) is attracted to those regions with relatively low environmental regulations. Our results are consistent with pollution haven seeking behaviour by foreign investors. In...

This paper analyses the role barriers to trade in the form of high transaction costs have on market participation and supply response in rural food markets in developing countries. We present an empirical application on a sample of households in the Tanzanian region of Kagera. Exploiting the availability of a long term panel dataset to develop an error components switching regression model we c...

Trade has been considered a condition for growth and development, a view that might have merits in explaining the rise of the Western world. I use a new data set from archival sources of eighteenth-century China to revisit this question. This analysis suggests previous studies of market integration, which attribute much growth to a reduction in transport costs, have overestimated these effects....
