U.S. economy have been the subject of much study. Understanding these sources is important because labor productivity growth is the key to increasing our economic standard of living. For example, the difference between a productivity growth rate of 3% a year and one of 1.5% a year means the difference between doubling our standard of living in 23 years instead of 46 years! Theory suggests four ...

We study how an optimal income tax and an optimal public-goods provision rule respond to preference and productivity shocks. A conventional Mirrleesian treatment is shown to provoke manipulations of the policy mechanism by individuals with similar interests. We therefore extend the Mirrleesian model so as to include a requirement of coalition-proofness. The main results are the following: first...

Labor productivity (LP) in the United States has gone from being procyclical to acyclical since the mid1980s. Using industry-level data, this paper first shows that total factor productivity (TFP), which is LP net of capital deepening, has also become much less correlated with output as well as inputs over the same period. Moreover, the bulk of the decline in aggregate TFP’s cyclicality is attr...

Information technology productivity has been studied on a macroeconomic level, a specific application level, as well as at a firm level. None of these studies has firmly determined whether there is an absence of productivity gains despite increased information technology expenditures (often known as the Productivity Paradox). This study reviews a specific year, 1995, using publicly available In...

This year PerCom received 208 submissions coming from 37 different countries from all five continents. The region including Europe, Middle East, and Africa was the major contributor (44%), followed by Asia/Pacific Area (29%) and North and Latin America (27%). These numbers confirm the growing interest in pervasive computing and PerCom as the international reference conference for researchers wo...

In a healthy economy, plant turnover increases aggregate productivity because efficient producers are more likely to survive. Given high entry and exit rates and the potential importance of turnover in accounting for aggregate productivity, in this paper we examine the determinants of plant exits and then examine how exits and other forms of output reallocation contribute to aggregate productiv...

"This paper steps back from the current political debate [in the United States] over the social security trust fund and examines the more general question of how serious a macroeconomic problem aging is and how policy should respond to it. We focus primarily on issues relating to saving and capital accumulation. We do not consider the broader question of whether the current U.S. national savi...

In this paper we present our work in progress on revisiting traditional DBMS mechanisms to manage space on native Flash and how it is administered by the DBA. Our observations and initial results show that: the standard logical database structures can be used for physical organization of data on native Flash; at the same time higher DBMS performance is achieved without incurring extra DBA overh...
