The paper employs an extended Yaari-Blanchard model of overlapping generations to study how the macroeconomy is affected over time by various demographic changes. It is shown that a proportional decline in fertility and death rates has qualitatively similar effects to capital income subsidies;...

The paper studies the dynamic macroeconomic effects of fiscal shocks of various duration (permanent and temporary) under different financing methods (lump-sum tax and government debt). To this end, we develop an intertemporal macroeconomic model for a small open economy, featuring monopolistic...

We combine two data sets to study price rigidity. The first consists of weekly time series of retail, wholesale, and spot prices for twelve products. These time series contain two exogenous cost shocks. We find that prices exhibit more rigidity in response to the second shock than the first. The...

We study the dynamics of an industry subject to aggregate demand shocks where the productivity of a firm's technology evolves stochastically over time. Each period, each firm, given the aggregate demand shock, the productivity of its technology, and the distribution of technology productivities...

We use local projections with granular instrumental variables to estimate the aggregate pass-through of costs into prices and how it is affected by industry concentration. On average, we find, prices increase above trend growth for three quarters after an exogenous cost shock, and the price...

This paper examines how changes in product market concentration, specifically firm exit, affect prices. I develop a model where firms have variable markups to show that the remaining firms increase their markups and prices after their competitors’ exit. The model predictions are tested using...

We examine the effect of increased customer industry competition on relationships with suppliers, using exogenous variation in industry-level tariffs. We find that customers facing significant tariff reductions increase output by increasing product purchases and maintaining longer relationship...

Using customer-supplier networks, we document a strong increase in stock return comovement between customer and supplier after the establishment of their relationship. This increase in comovement is mainly associated with cash flow news and firm-specific information. We find that the...

If managers are risk-averse and compensation schemes are not directly linked to shareholder wealth, incentives to allocate effort to manage effects of relative and macroeconomic shocks may be distorted. In this paper we develop a simple model to identify factors that determine the optimal...

Using an annual panel of U.S. states over the period 1982-2014, we estimate the response of macroeconomic variables to a shock to the number of new firms (startups). We find that these shocks have significant effects that persist for many years on real gross domestic product, productivity and...
