Topological data analysis (TDA) is an emerging method that has gained popularity in recent years, especially in the field of data science. TDA offers a powerful tool for analyzing complex and high-dimensional data, making it a promising method for researchers in economics. In this paper, we...

Demographic and economic characteristics have been shown to provide important predictive power for determining a country’s success in the Olympic Games. This paper extends such research, providing a set of predictions for the gold medals and total medals each country will win at the 2006...

The topic of economic growth and convergence of countries has been an active topic in the 1990's. This paper investigates the question of whether there is any empirical evidence that countries are converging, with respect to their relative incomes, over time. To test for convergence, the...

Recent results of Cribari-Neto and Zarkos show that bootstrap methods can be successfully used to estimate a heteroskedasticity robust covariance matrix estimator. We show that their bootstrap estimator can be calculated directly, without bootstrapping, and that inference based on it may not be...

Simulation-based estimation methods have become more wideky used in recent years. We propose a set of tests for structural Change in model estimates via Simulated Method of Moments (see Duffie and Singleton (1993)). These tests extend the recent work of Andrews (1993) and Sowell (1996a, b) which...

The application of econometric analysis to the process of economic policy formulation is considered. A framework is provided by the theory of reduction, specifically reductions where key information losses would invalidate policy.

Macroeconomic practitioners frequently work with multivariate time series models such as VARs, factor augmented VARs as well as time-varying parameter versions of these models (including variants with multivariate stochastic volatility). These models have a large number of parameters and, thus,...

We examine theoretically and empirically the properties of the equilibrium wage function and its implications for policy. Our emphasis is on how the researcher approaches economic and policy questions when there is labor market heterogeneity leading to a set of wages. We focus on the application...

Economic incentives play an important role in occupational safety and health, affecting the behavior and decisions of workers, firms and government. This monograph discusses factors that affect workers' decisions about whether to choose risky jobs, how careful to be on the job, and how long to...

In this paper we analyze the sensitivity of unit root inference to nonlinear transformations through Bayesian techniques. We make joint inference about the Box-Cox transformation, which includes the cases yt and log(yt), and the unit root. When we apply our method to the fourteen Nelson-Plosser...
