This paper considers issues related to testing for multiple structural changes in cointegrated systems. We derive the limiting distribution of the Sup-Wald test under mild conditions on the errors and regressors for a variety of testing problems. We show that even if the coefficients of the...

This paper considers the problem of testing for structural changes in the trend function of a univariate time series without any prior knowledge as to whether the noise component is stationary or contains an autoregressive unit root. We propose a new approach that builds on the work of Perron...

Perron (1989) introduced unit root tests valid when a break at a known date in the trend function of a time series is present, which are invariant to the magnitude of the shift in level and/or slope and to allow them under both the null and alternative hypotheses. The subsequent literature...

This paper introduces bias-corrected estimators for nonlinear panel data models with both time invariant and time varying heterogeneity. These include limited dependent variable models with both unobserved individual effects and endogenous explanatory variables, and sample selection models with...

Risk adjustment deters selection and helps to assure fair and efficient payments among health insurers or capitated provider groups. However, since conventional risk adjustment allocates funds among insurers or regions according to current population health status, it does not reward — indeed,...

Experiments on time preference document numerous .ndings that seem to con- tradict the standard model of intertemporal choice. These .ndings are based on how subjects choose between delayed rewards. This paper shows that if subjects integrate such rewards with their consumption plans, and expect...

This paper examines the impact of investment-specific technological change on labor composition in U.S. manufacturing industries from 1974 to 1994. I show that investmentspecific technological change increases the relative demand of non-production workers to production workers, while TFP growth...

Temptation is the conflict between one’s desires (temptation preference) and one’s view of what choices he should make (normative preference). In seminal work, Gul and Pesendorfer [7, 8] provide foundations for a model of temptation on the basis of the idea that temptation creates a...

We study the effect of variation in interest rates on investment spending, employing a large panel data set that links yields on outstanding corporate bonds to the issuer income and balance sheet statements. The bond price data—based on trades in the secondary market—enable us to construct a...

Many economic decisions can be described as an option exercise or optimal stopping problem under uncertainty. Motivated by experimental evidence such as the Ellsberg Paradox, we follow Knight (1921) and distinguish risk from uncertainty. To afford this distinction, we adopt the multiple-priors...
