This note proposes a tool to investigate and demonstrate the adequacy of the central limit theorem in small samples. The suggested testing procedure provides a method to investigate if the mean estimator is approximately normally distributed, given data and sample size at hand. This is important...

The LM type linearity test for STAR nonlinearities is severely distorted when the process is governed by conditional heteroskedasticity. In order to correct the test we propose a parametric bootstrap. It is shown, by means of Monte Carlo methods, that the bootstrap test is almost exact.

The full Bayesian treatment of error component models typically relies on data augmentation to produce the required inference. Never stricly necessary a direct approach is always possible though not necessarily practical. The mechanics of direct sampling are outlined and a template for including...

A product set of pure strategies is a prep set ("prep" is short for "preparation") if it contains at least one best reply to any consistent belief that a player may have about the strategic behavior of his opponents. Minimal prep sets are shown to exists in a class of strategic games satisfying...

Changes in the seasonal patterns of macroeconomic time series may be due to the effects of business cycle fluctuations or to technological and institutional change or both. We examine the relative importance of these two sources of change in seasonality for quarterly industrial production series...

Within most organizations, agents may spend time on a variety of tasks, productive and redistributive. In this paper, I derive an optimal multi-task incentive scheme under the realistic assumption that agents have limited liability. The wage level is shown to increase with an agent's discretion...

We examine deviations from the law of one price (LOP) with price data from duty-free outlets where each product, at a given location, has its price quoted in (at least) two currencies. Reluctance to adjust relative prices for "small" deviations from LOP allows prices to differ by up to 7-10...

The private manufacturing sector has been called upon to play a key role in the transformation and development of the Vietnamese economy since the launching of market oriented reforms a decade ago. Drawing on a comprehensive survey in 1997 of some 500 non-state manufacturing enterprises in...

Intresse och användning av hälsoekonomiska utvärderingar som underlag vid beslut om pris och subentionering av läkemedel ökar i de flesta länder. Många länder har infört mer eller mindre formella krav på hälsoekonomisk dokumentation inför sådana beslut och ett flertal länder och...

This paper examines aggregate savings in a general equilibrium model where infinitely lived households face volatile (and possibly uncertain) income paths, hold a risk-free asset, and face a liquidity constraint. I first show that the equilibrium capital stock in an economy without uncertainty,...
