An attempt is made to estimate a state space model of investment and borrowing in a Bayesian framework and extract the unobservable agency cost of Japanese firms by firm size. Our estimates of the agency cost exhibited a declining trend in the late 80s and then switched to an increasing trend in...

Corruption is a function of its return relative to engaging in productive activities. This paper presents an approach for thinking about the institutional features of societies and the resulting amount of corruption. The empirical results suggest that political competition is more important than...

Economic interdependence of heterogeneous habit forming consumers is examined by using a two-country model. Due to endogenous interest rate adjustments, consumption-habit dynamics in one country are affected by the other country’s habits and preferences. To characterize the interactive...

It is a widely shared view in the population health field that the future of the analysis of population health lies in the assessment both of the length of life and health-adjusted quality of life, and the parallel examination of the average health and health distribution within a population....

Both human capital accumulation and Lazear contracts can explain the raising wage of salary/wage worker through job experience or tenure. To distinguish between these two effects, Lazear and Moore (1984) used self-employed workers’ wage growth to partial out the effect of human capital...

This paper analyzes purchasing power parity and uncovered interest parity in the laboratory. It finds strong evidence that purchasing power parity, covered interest parity, and uncovered interest parity hold. Subjects are endowed with an intrinsically useless (green) currency that can be used to...

This paper provides a review of some recent theoretical results for time series models with GARCH errors, and is directed towards practitioners. Starting with the simple ARCH model and proceeding to the GARCH model, some results for stationary and nonstationary ARMA-GARCH are summarized. Various...

Least squares (LS) and maximum likelihood (ML) estimation are considered for unit root processes with GARCH (1, 1) errors. The asymptotic distributions of LS and ML estimators are derived under the condition alpha + beta 1. The former has the usual unit root distribution and the latter is a...

This paper examines stationary and nonstationary time series by formally testing for the presence of unit roots and seasonal unit roots prior to estimation, model selection and forecasting. Various Box-Jenkins Autoregressive Integrated Moving Average (ARIMA) models are estimated over the period...

This paper investigates some structural properties of a family of GARCH processes. A simple sufficient condition for the existence of the αδ-order stationary solution of the processes is derived, where α ∈ (0, 1] and δ 0. The solution is strictly stationary and ergodic, and the causal...
