This paper examines the Aghion and Howitt (1992) ''creative destruction'' endogenous growth model in an open economy setting. We consider four alternative trade regimes. The first two regimes allow the monopoly producer of the intermediate good to attain worldwide monopoly rents. In the first of...

A semiparametric fixed effects model is introduced to describe the nonlinear trending phenomenon in panel data analysis and it allows for the cross-sectional dependence in both the regressors and the residuals. A semiparametric profile likelihood approach based on the first-stage local linear...

This paper proposes a model specification testing procedure for parametric specification of the conditional mean function in a nonlinear time series model with long–range dependence. An asymptotically normal test is established even when long–range dependence is involved. In order to...

Every decade or so, food becomes newsworthy globally because of a price spike, either upwards (hurting consumers, as in 1973 and 2008) or downwards (hurting farmers in open economies, as in 1986). Most such price spikes are a consequence of major policy shifts, since local weather-induced supply...

This paper is concerned with developing a nonparametric time-varying coefficient model with fixed effects to characterize nonstationarity and trending phenomenon in nonlinear panel data analysis. We develop two methods to estimate the trend function and the coefficient function without taking...

This paper presents a selective survey of volatility topics, with emphasis on the measurement of volatility and a discussion of some of the most important time series models commonly employed in its modelling. In particular, the paper details the long memory characteristics of volatility, and...

We propose a sound approach to bandwidth selection in nonparametric kernel testing. The main idea is to find an Edgeworth expansion of the asymptotic distribution of the test concerned. Due to the involvement of a kernel bandwidth in the leading term of the Edgeworth expansion, we are able to...

In this paper we examine some properties of the Benge and Wells (B-W) (1998a,b) formulation of a small open economy version of the Solow-Swan growth model. We suggest a simple method for classifying economies as capital importers or exporters (net debtors or creditors) in the steady state and...

For decades, earnings from farming in many developing countries have been depressed by a pro-urban bias in own-country policies, as well as by governments of richer countries favoring their farmers with import barriers and subsidies. Both sets of policies reduce national and global economic...

We study the allocation of collectively owned indivisible goods when monetary transfers are possible. We restrict our attention to incentive compatible mechanisms which allocate the goods efficiently. Among these mechanisms, we characterize those that respect welfare lower bounds. The main...
