In randomized clinical trials where the effects of post-randomization factors are of interest, the standard regression analyses are biased due to unmeasured confounding. The instrumental variables (IV; Angrist et al., 1996) and G-estimation procedures under structural nested mean models (SNMMs;...

This paper has two main contributions. Firstly, we introduce a new approach, the latent instrumental variables (LIV) method, to estimate regression coefficients consistently in a simple linear regression model where regressor-error correlations (endogeneity) are likely to be present. The LIV...

In recent decades there has been a substantial increase in the scale of production and the use of production contracts in the hog sector. This paper explores empirically whether these two phenomena are related by examining whether the use of production contracts has allowed finish hog operations...

MF loans react to economic conditions but are also sensitive to political-economy variables. Loans tend to be larger and more frequent when a country has a bigger quota and more professional staff at the IMF and when a country is more connected politically and economically to the United States...

Results from this study indicate that non-adherence in hemodialysis (HD) sessions marginally affects health care costs and does not significantly increase the likelihood of kidney transplantation failure. This dissertation explores the impacts of non-adherence in HD sessions on health care costs...

In applied work economists often seek to relate a given response variable y to some causal parameter mu* associated with it. This parameter usually represents a summarization based on some explanatory variables of the distribution of y, such as a regression function, and treating it as a...

Using information of the balance sheets of Spanish banks between 1995 and 2009, we estimate the average impact of current and anticipated changes in banks’ capital on fi rm lending. We isolate the role of credit supply factors using the variation in capital growth associated to the...

En este trabajo se estudia cómo los estimadores que se utilizan para imputar consumo en datos provenientes de encuestas son inconsistentes a causa de error de medida en la variable de consumo. Estudios anteriores sugieren instrumentar consumo para superar este problema. El presente estudio...

En este estudio analizamos el impacto de las restricciones al crédito en la inversión, los inventarios y el crecimiento empresarial con una muestra grande de pequeñas y medianas empresas de 12 economías europeas durante el período 2014-2016. Los datos provienen de la Encuesta sobre el...

En este documento se proponen nuevos métodos con el objetivo de construir intervalos de confianza para el sesgo del estimador de mínimos cuadrados en dos etapas y para la distorsión del tamaño del test de Wald asociado a los modelos de variables instrumentales. Es importante destacar que...
