The U.S. shale boom has profoundly increased crude oil movements by both pipelines–the traditional mode of transportation–and railroads. This paper develops a model of how pipeline investment and railroad use are determined in equilibrium, emphasizing how railroads' flexibility allows them...

This paper constructs new estimates of the air pollution and greenhouse gas costs from long-distance movement of petroleum products by rail and pipelines. While crude oil transportation has generated intense policy debate about rail and pipeline spills and accidents, important externalities –...

In this paper, I combine data on incidents associated with rail transportation of crude oil and detailed data on rail shipments to appraise the relation between increased use of rail to transport crude oil and the risk of safety incidents associated with those shipments. I find a positive link...

Contemporary observers viewed the recession that began in the summer of 1929 as nothing extraordinary. Recent analyses have shown that the subsequent large deflation was econometrically forecastable, implying that a driving force in the depression was the high expected real interest rates faced...

Grain shippers and political figures in North Dakota and nearby states have voiced concern that the dramatic increases in shipments of crude oil by rail have caused service delays and higher costs. We investigate the potential impact of crude shipments on grain markets accounting for harvest...

Researchers interested in estimating productivity can choose from an array of methodologies, each with its strengths and weaknesses. Methods differ by the assumptions they rely on and imply very different calculations. I compare five widely used techniques: (a) index numbers, (b) data...

We study how innovation and technology diffusion interact to endogenously determine the shape of the productivity distribution and generate aggregate growth. We model firms that choose to innovate, adopt technology, or produce with their existing technology. Costly adoption creates a spread...

This study documents a strong inverse relationship between accident rates and production in a sample of eleven firms in the same narrowly defined industry classification. Given the detailed set of input controls and controls for plant-specific and time-specific factors used in the analysis, the...

Antebellum critics of slavery argued that it was responsible for the relative inefficiency of free southern farms. We examine this issue, employing a stochastic production function, which allows us to distinguish between technological superiority and technical inefficiency, and controlling for...

This paper examines micro-level channels of how financial development can affect macroeconomic outcomes like the level of income and export intensity. We investigate theoretically and empirically how financial constraints affect a firm's innovation and export activities, using unique firm survey...
