In this paper we develop a nonparametric estimation technique for semiparametric transformation models of the form: H(Y)=P(Z)+X'B+U where H,P and B and are unknown and the variables (Y,Z) are endogenous. Identification of the model and asymptotic properties of the estimator are analyzed under...

I propose a game of signed network formation, where agents make friends to coerce payoffs from enemies with fewer friends. The model accounts for the interplay between friendship and enmity. Nash equilibrium configurations are such that, either everyone is friends with everyone, or agents can be...

This paper studies the aid allocation rule used by major development agencies, and investigates optimal allocations when recipients are neoclassical economies undergoing transition dynamics. When recipients face aid absorption constraints, allocations that favor poorer recipients are not always...

I embed the pricing model proposed by Dixon and Kara (2011a, b) (i.e. a Generalized Taylor Economy (GTE)) into a state of the art instance of New Keynesian economics (e.g. Christiano, Eichenbaum and Evans (2005) and Smets and Wouters (2007)). The GTE is built to account for one of the most...

Empirical evidence shows that vertically integrated producers are more productive, bigger and are matched to better suppliers (with high productivity and size). I present a dynamic stochastic model of an industry with heterogeneous firms interacting as buyers and sellers, and market frictions...

This paper examines the dynamic effects of oil price shocks in addition to the aggregate supply and demand shocks on macroeconomic fluctuations in four sample economies: Indonesia, Malaysia, Pakistan and Thailand. We aim to discover whether oil price shocks play a crucial role in explaining...

This paper investigates the identification and estimation of the least square linear predictor for the conditional expectation of an outcome variable Y given covariates (X;Z0) from data consisting of two independent random samples; the first sample contains replications of the variables (Y;Z0)...

This paper presents a simple model of strategic network formation with local com- plementarities in effort levels and positive local externalities. Equilibrium networks display - other than the complete and the empty network - a core-periphery structure, which is commonly observed in empirical...

According to Acton: "Power corrupts and absolute power corrupts absolutely". We study the implications of Acton's dictum in models where citizens vote (for three parties) and governments then form in a series of elections. In each election, parties have fixed tastes for graft, which affect...

Using a dynamic stochastic general equilibrium (DSGE) model that accounts for credit constraints, we study the effects of fiscal stimulus on the macroeconomy. We show that the presence of credit constraints results in larger fiscal multipliers than indicated by the standard DSGE models. If...
