Economic Reforms and Productivity-Enhancing Reallocation in the Post-Soviet Transition How do economic reforms affect resource reallocation processes and their contributions to productivity growth? This paper studies the consequences of enterprise privatization and liberalization of product markets, labor markets, and imports in the former Soviet Republics of Russia and Ukraine. Analyzing inter...

We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A key feature is the selection between highand low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using detailed US Census micro data on firm-level output, R&D and patenting. The model provides a good fit to the dynamics of...

Emerging cloud markets like spot markets and batch computing services scale up services at the granularity of whole VMs. In this paper, we observe that GPU workloads underutilize GPU device memory, leading us to explore the benefits of reallocating heterogeneous GPUs within existing VMs. We outline approaches for upgrading and downgrading GPUs for OpenCL GPGPU workloads, and show how to minimiz...

We study a dynamic allocation problem that arises in various scenarios where mobile clients joining and leaving the system have to communicate with static stations via radio transmissions. Restrictions are a maximum delay, or laxity, between consecutive client transmissions and a maximum bandwidth that a station can share among its clients. We study the problem of assigning clients to stations ...

We present a software toolbox for symmetric band reduction, together with a set of testing and timing drivers. The toolbox contains routines for the reduction of full symmetric matrices to banded form and the reduction of banded matrices to narrower banded or tridiagonal form, with optional accumulation of the orthogonal transformations, as well as repacking routines for storage rearrangement. ...

We investigate the problem of repacking stations in the FCC’s upcoming, multi-billion-dollar “incentive auction”. Early efforts to solve this problem considered mixed-integer programming formulations, which we show are unable to reliably solve realistic, national-scale problem instances. We describe the result of a multi-year investigation of alternatives: a solver, SATFC, that has been adopted...

How do firms adjust their balance sheets and reallocate capital stock in response to recurrent productivity or profitability shocks? Why does capital reallocation fluctuate procyclically, while the potential benefits to reallocate appear to be countercyclical? To answer these questions, this paper develops a tractable dynamic general equilibrium model. In the model, firms face idiosyncratic pro...

We revisit measurement of Employer-to-Employer (EE) transitions, the main engine labor market competition and employment reallocation, in monthly Current Population Survey (CPS). follow Fallick Fleischman (2004) exploit a key survey question introduced with 1994 CPS redesign. detect sudden sharp increase incidence missing answers to this starting 2007, when U.S. Census Bureau change methodology...
