While much economic policy presumes that more information infrastructure yields higher economic returns, little empirical work measures the magnitudes of these returns. We examine investment by local exchange telephone companies in fiber optic cable, ISDN lines and signal seven software,...

We propose a new classification of consumption goods into nondurable goods, durable goods and a new class which we call "memorable" goods. A good is memorable if a consumer can draw current utility from its past consumption experience through memory. We propose a novel consumption-savings model...

We develop a flexible semiparametric time series estimator that is then used to assess the causal effect of monetary policy interventions on macroeconomic aggregates. Our estimator captures the average causal response to discrete policy interventions in a macro-dynamic setting, without the need...

This paper examines demand systems where the demand for a good depends on other prices only through a common price aggregator (a scalar function of all prices). We refer to this property as ``generalized separability'' and provide the functional forms of demand that this property implies when...

Economists routinely make functional form assumptions about consumer demand to obtain welfare estimates. How sensitive are welfare estimates to these assumptions? We answer this question by providing bounds on welfare that hold for families of demand curves commonly considered in different...

As is well known, during the pandemic recession firms directly exposed to the virus, i.e. the "contact" sector, contracted sharply and recovered slowly relative to the rest of the economy. Less understood is how firms that "won" by offering safer substitutes for contact sector goods have...

This paper measures the impact of nonassumable, fixed-rate, long-term mortgage financing on household mobility and housing demand during a period of accelerating inflation (l965_71l). We calculate that typical households who bought houses during the l96l7l period and utilized this type of...

We propose new methods to model behavior and conduct welfare analysis in complex environments where some choices are unlikely to reveal preferences. We develop a mixture-of-experts model that incorporates heterogeneity in consumers' preferences and in their choice processes. We also develop a...

The rapid rise in e-cigarette use rates among high school students in the United States is a significant source of public policy concern for many states. This paper is the first study to examine the impact of state tobacco control spending on the demand for vaping products by high school...

We use U.S. household-level bank account data to investigate the heterogeneous effects of the pandemic on spending and savings. Households across the income distribution all cut spending from March to early April. Since mid April, spending has rebounded most rapidly for low-income households. We...
