Macroeconomic Fluctuations And Poverty, Philip N. Jefferson, Kunhee Kim Nov 2012

Macroeconomic Fluctuations And Poverty, Philip N. Jefferson, Kunhee Kim

Health Care Management Papers

This article examines the dynamic relationship between macroeconomic performance and measures of poverty in the United States. The article is organized as follows. Section 2 presents insights on the relationship between poverty and macroeconomic performance that emerge from the literature. The emphasis is on empirical studies from 1986 to 2011. Section 3 provides a snapshot of the change in poverty over National Bureau of Economic Research-dated recessions for a variety of poverty measures. Section 4 uses vector autoregressions (VARs) to characterize the response of poverty to innovations in various social indicators and measures of macroeconomic performance. Section 5 expands the ...


Financial Frictions, Propagation Of Shocks, And Macroeconomic Volatility, Cristina Fuentes-Albero May 2010

Financial Frictions, Propagation Of Shocks, And Macroeconomic Volatility, Cristina Fuentes-Albero

Publicly Accessible Penn Dissertations

I study the evolution of aggregate volatility in the US during the postwar period by assessing the relative role played by financial shocks, technological progress, and changes in the financial system. Balance-sheet variables of firms have been characterized by greater volatility since the early 1970s. This Financial Immoderation has coexisted with the so-called Great Moderation, which refers to the slowdown in volatility of real and nominal variables since the mid 1980s. In the second chapter, I study the moderation in real variables calibrating a real business cycle model with two technology shocks. I consider several statistical specifications for technological progress ...


Essays In Estimation Of Dynamic Stochastic General Equilibrium Models, Maxym Kryshko May 2010

Essays In Estimation Of Dynamic Stochastic General Equilibrium Models, Maxym Kryshko

Publicly Accessible Penn Dissertations

Dynamic factor models (DFM) and dynamic stochastic general equilibrium (DSGE) models are widely used for empirical research in macroeconomics. The empirical factor literature argues that the co-movement of large panels of macroeconomic and financial data can be captured by relatively few common unobserved factors. Similarly, the dynamics in DSGE models are often governed by a handful of state variables and exogenous processes such as latent preference and/or technology shocks. A general topic of this dissertation is the estimation of DSGE models on a rich panel of macroeconomic and financial data by combining a DSGE with a dynamic factor model ...


Essays On The Macroeconomics Of Incomplete Information, Leonardo Melosi May 2010

Essays On The Macroeconomics Of Incomplete Information, Leonardo Melosi

Publicly Accessible Penn Dissertations

In the first chapter, I develop and estimate a dynamic general equilibrium model with imperfectly informed firms in the sense of Woodford (2002). The model has two aggregate shocks: a monetary policy shock and a technology shock. Firms observe idiosyncratic noisy signals about these shocks and face strategic complementarities in price setting. In this environment, agents' "forecasting the forecasts of others" can produce realistic dynamics of model variables, with associated highly persistent real effects of monetary shocks and delayed effects of such shocks on inflation. The paper provides a full Bayesian analysis of the model, revealing that it can capture ...


Beyond Computation: Information Technology, Organizational Transformation And Business Performance, Erik Brynjolfsson, Lorin M. Hitt Jan 2000

Beyond Computation: Information Technology, Organizational Transformation And Business Performance, Erik Brynjolfsson, Lorin M. Hitt

Operations, Information and Decisions Papers

To understand the economic value of computers, one must broaden the traditional definition of both the technology and its effects. Case studies and firm-level econometric evidence suggest that: 1) organizational "investments" have a large influence on the value of IT investments; and 2) the benefits of IT investment are often intangible and disproportionately difficult to measure. Our analysis suggests that the link between IT and increased productivity emerged well before the recent surge in the aggregate productivity statistics and that the current macroeconomic productivity revival may in part reflect the contributions of intangible capital accumulated in the past.
