The tests introduced by Ng and Perron (2001, Econometrica) have the drawback that for non-local alternatives the power can be very small. The aim of this note is to point out an easy solution to this power reversal problem, which in addition leads to tests having an exact size even closer to...

We find that the Andrews and Ploberger’s (1996) tests have unit local power against the nearly integrated, nearly white noise process (ref. Nabeya and Perron (1994)). Therefore, compared with the stationary local alternatives, higher power is expected when testing against such process. Monte...

The main purpose of this paper is to estimate panel data models with endogenous regressors and nonadditive unobserved individual heterogeneity including, for example, linear and nonlinear models where all the parameters can vary across individuals. The quantities of interest are means,...

This paper provides a dynamic rational expectations equilibrium model in which investors have heterogeneous information and investment opportunities. Informed investors privately receive advance information that is useful for predicting future earnings but is unrelated to current earnings. This...

This paper studies optimal consumption and portfolio choice in a Mertonstyle model with incomplete information when there is a distinction between ambiguity and risk. The latter distinction is afforded by adoption of recursive multiple-priors utility. The fundamental issues are: (i) How does the...

Entrepreneurs face significant non-diversifiable business risks. We build a dynamic incompletemarkets model of entrepreneurial firms to demonstrate the important implications of nondiversifiable risks for entrepreneurs’ interdependent consumption, portfolio allocation, financing, investment,...

In this paper we present a recursive method for the computation of dynamic competitive equilibria in models with heterogeneous agents and market frictions. This method is based on a convergent operator over an expanded set of state variables. The fixed point of this operator defines the set of...

In this paper, we develop a new censored quantile instrumental variable (CQIV) estimator and describe its properties and computation. The CQIV estimator handles censoring semi-parametrically in the tradition of Powell (1986), and it generalizes standard censored quantile regression (CQR) methods...

Empirical and experimental evidence documents that money illusion is persistent and widespread. This paper incorporates money illusion into two stochastic continuous-time monetary models of endogenous growth. Motivated by psychology, we model an agent's money illusion behavior by assuming that...

We develop a dynamic general equilibrium model to study the impact of the 2003 dividend and capital gains tax cuts. Firms are heterogeneous in productivity and make investment and financing decisions subject to capital adjustment costs, equity issuance costs, and collateral constraints. Our...
