Why Do Cities Matter? Local Growth and Aggregate Growth
Chang-Tai Hsieh & Enrico Moretti
NBER Working Paper, May 2015
Abstract:
We study how growth of cities determines the growth of nations. Using a spatial equilibrium model and data on 220 US metropolitan areas from 1964 to 2009, we first estimate the contribution of each U.S. city to national GDP growth. We show that the contribution of a city to aggregate growth can differ significantly from what one might naively infer from the growth of the city’s GDP. Despite some of the strongest rate of local growth, New York, San Francisco and San Jose were only responsible for a small fraction of U.S. growth in this period. By contrast, almost half of aggregate US growth was driven by growth of cities in the South. We then provide a normative analysis of potential growth. We show that the dispersion of the conditional average nominal wage across US cities doubled, indicating that worker productivity is increasingly different across cities. We calculate that this increased wage dispersion lowered aggregate U.S. GDP by 13.5%. Most of the loss was likely caused by increased constraints to housing supply in high productivity cities like New York, San Francisco and San Jose. Lowering regulatory constraints in these cities to the level of the median city would expand their work force and increase U.S. GDP by 9.5%. We conclude that the aggregate gains in output and welfare from spatial reallocation of labor are likely to be substantial in the U.S., and that a major impediment to a more efficient spatial allocation of labor are housing supply constraints. These constraints limit the number of US workers who have access to the most productive of American cities. In general equilibrium, this lowers income and welfare of all US workers.

The Passthrough of Labor Costs to Price Inflation
Ekaterina Peneva & Jeremy Rudd
Federal Reserve Working Paper, May 2015
Abstract:
We use a time-varying parameter/stochastic volatility VAR framework to assess how the passthrough of labor costs to price inflation has evolved over time in U.S. data. We find little evidence that changes in labor costs have had a material effect on price inflation in recent years, even for compensation measures where some degree of passthrough to prices still appears to be present. Our results cast doubt on explanations of recent inflation behavior that appeal to such mechanisms as downward nominal wage rigidity or a differential contribution of long-term and short-term unemployed workers to wage and price pressures.

Journal of International Economics, forthcoming
Abstract:
We develop a two-country general equilibrium model, in which heterogeneous firms offshore routine tasks to a low-wage host country. In the presence of fixed costs for offshoring the most productive firms self-select into offshoring, which leads to a reallocation of domestic labor towards less productive uses if offshoring costs are high. As a consequence domestic welfare may fall. The reallocation effect is reversed and domestic welfare rises if offshoring costs are low. The aggregate income distribution, comprising wages and entrepreneurial incomes, becomes more unequal with offshoring.

Coal Mining, Economic Development, and the Natural Resources Curse
Michael Betz et al.
Energy Economics, July 2015, Pages 105-116
Abstract:
Coal mining has a long legacy of providing needed jobs in isolated communities but it is also associated with places that suffer from high poverty and weaker long-term economic growth. Yet, the industry has greatly changed in recent decades. Regulations, first on air quality, have altered the geography of coal mining, pushing it west from Appalachia. Likewise, technological change has reduced labor demand and has led to relatively new mining practices, such as invasive mountain-top approaches. Thus, the economic footprint of coal mining has greatly changed in an era when the industry appears to be on the decline. This study investigates whether these changes along with coal’s “boom/bust” cycles have affected economic prosperity in coal country. We separately examine the Appalachian region from the rest of the U.S. due to Appalachia’s unique history and different mining practices. Our study takes a new look at the industry by assessing the winners and losers of coal development around a range of economic indicators and addressing whether the natural resources curse applies to contemporary American coal communities. The results suggest that modern coal mining has rather nuanced effects that differ between Appalachia and the rest of the U.S. We do not find strong evidence of a resources curse, except that coal mining has a consistent inverse association with measures linked to population growth and entrepreneurship, and thereby future economic growth.

Place-Based Programs and the Geographic Dispersion of Employment
Matthew Freedman
Regional Science and Urban Economics, July 2015, Pages 1-19
Abstract:
Government efforts to improve local economic conditions by encouraging private investment in targeted communities could affect the broader geographic distribution of employment in a region, especially to the extent that subsidized businesses face few constraints on whom they hire. This paper examines the labor market impacts of investment subsidized by the U.S. federal government’s New Markets Tax Credit (NMTC) program, which provides tax incentives to promote business investment in low-income neighborhoods. To identify the program’s effects, I exploit a discontinuity in the rule determining the eligibility of census tracts for NMTC-subsidized investment. Using rich administrative data on workers’ residence and workplace locations, I find evidence that many of the new jobs created in areas that receive subsidized investment do not go to residents of targeted neighborhoods. The results suggest that the local economic benefits of place-based programs may be diluted when subsidized businesses have scope to hire from broader regional labor markets.

Recent U.S. Labor Force Dynamics: Reversible or Not?
Ravi Balakrishnan et al.
IMF Working Paper, April 2015
Abstract:
The U.S. labor force participation rate (LFPR) fell dramatically following the Great Recession and has yet to start recovering. A key question is how much of the post-2007 decline is reversible, something which is central to the policy debate. The key finding of this paper is that while around ¼-⅓ of the post-2007 decline is reversible, the LFPR will continue to decline given population aging. This paper’s measure of the “employment gap” also suggests that labor market slack remains and will only decline gradually, pointing to a still important role for stimulative macro-economic policies to help reach full employment. In addition, given the continued downward pressure on the LFPR, labor supply measures will be an essential component of the strategy to boost potential growth. Finally, stimulative macroeconomic and labor supply policies should also help reduce the scope for further hysteresis effects to develop (e.g., loss of skills, discouragement).

The Effect of Extended Unemployment Insurance Benefits: Evidence from the 2012-2013 Phase-Out
Henry Farber, Jesse Rothstein & Robert Valletta
American Economic Review, May 2015, Pages 171-176
Abstract:
Unemployment Insurance benefit durations were extended during the Great Recession, reaching 99 weeks for most recipients. The extensions were rolled back and eventually terminated by the end of 2013. Using matched CPS data from 2008-2014, we estimate the effect of extended benefits on unemployment exits separately during the earlier period of benefit expansion and the later period of rollback. In both periods, we find little or no effect on job-finding but a reduction in labor force exits due to benefit availability. We estimate that the rollbacks reduced the labor force participation rate by about 0.1 percentage point in early 2014.

Untangling Trade and Technology: Evidence from Local Labour Markets
David Autor, David Dorn & Gordon Hanson
Economic Journal, May 2015, Pages 621-646
Abstract:
We juxtapose the effects of trade and technology on employment in US local labour markets between 1980 and 2007. Labour markets whose initial industry composition exposes them to rising Chinese import competition experience significant falls in employment, particularly in manufacturing and among non-college workers. Labour markets susceptible to computerisation due to specialisation in routine task-intensive activities instead experience occupational polarisation within manufacturing and non-manufacturing but do not experience a net employment decline. Trade impacts rise in the 2000s as imports accelerate, while the effect of technology appears to shift from automation of production activities in manufacturing towards computerisation of information-processing tasks in non-manufacturing.

Human Capital Quality and Aggregate Income Differences: Development Accounting for U.S. States
Eric Hanushek, Jens Ruhose & Ludger Woessmann
NBER Working Paper, June 2015
Abstract:
Although many U.S. state policies presume that human capital is important for state economic development, there is little research linking better education to state incomes. In a complement to international studies of income differences, we investigate the extent to which quality-adjusted measures of human capital can explain within-country income differences. We develop detailed measures of state human capital based on school attainment from census micro data and on cognitive skills from state- and country-of-origin achievement tests. Partitioning current state workforces into state locals, interstate migrants, and immigrants, we adjust achievement scores for selective migration. We use the new human capital measures in development accounting analyses calibrated with standard production parameters. We find that differences in human capital account for 20-35 percent of the current variation in per-capita GDP among states, with roughly even contributions by school attainment and cognitive skills. Similar results emerge from growth accounting analyses.

Opening the Black Box of the Matching Function: The Power of Words
Ioana Elena Marinescu & Ronald Wolthoff
University of Chicago Working Paper, May 2015
Abstract:
How do employers attract the right workers? How important are posted wages vs. other job characteristics? Using data from the leading job board CareerBuilder.com, we show that most vacancies do not post wages, and, for those that do, job titles explain more than 90% of the wage variance. Job titles also explain more than 80% of the across-vacancies variance in the education and experience of applicants. Finally, failing to control for job titles leads to a spurious negative elasticity of labor supply. Thus, our results uncover the previously undocumented power of words in the job matching process.

House Prices, Home Equity Borrowing, and Entrepreneurship
Stefano Corradin & Alexander Popov
Review of Financial Studies, forthcoming
Abstract:
This paper shows that housing wealth helps alleviate credit constraints for potential entrepreneurs by enabling home owners to extract equity from their property and invest it in their business. Using a large U.S. individual-level survey dataset for the 1996-2006 period, we find that a 10% increase in home equity raises the share of individuals who transition into self-employment each year from 1% to 1.07%. Our results persist when we use proxies for aggregate housing demand shocks and for the topological elasticity of housing supply to generate variation in home equity that is orthogonal to entrepreneurial choice.

David Autor et al.
NBER Working Paper, May 2015
Abstract:
Combining administrative data from the U.S. Army, Department of Veterans Affairs (VA) and the U.S. Social Security Administration, we analyze the effect of the VA’s Disability Compensation (DC) program on veterans’ labor force participation and earnings. The largely unstudied Disability Compensation program currently provides income and health insurance to almost four million veterans of military service who suffer service-connected disabilities. We study a unique policy change, the 2001 Agent Orange decision, which expanded DC eligibility for Vietnam veterans who had served in-theatre to a broader set of conditions such as type 2 diabetes. Exploiting the fact that the Agent Orange policy excluded Vietnam era veterans who did not serve in-theatre, we assess the causal effects of DC eligibility by contrasting the outcomes of these two Vietnam-era veteran groups. The Agent Orange policy catalyzed a sharp increase in DC enrollment among veterans who served in-theatre, raising the share receiving benefits by five percentage points over five years. Disability ratings and payments rose rapidly among those newly enrolled, with average annual non-taxed federal transfer payments increasing to $17K within five years. We estimate that benefits receipt reduced labor force participation by 18 percentage points among veterans enrolled due to the policy, though measured income net of transfer benefits rose on average. Consistent with the relatively advanced age and diminished health of Vietnam era veterans in this period, we estimate labor force participation elasticities that are somewhat higher than among the general population.

Xuan Chen & Carlos Flores
Journal of Business & Economic Statistics, forthcoming
Abstract:
Randomized and natural experiments are commonly used in economics and other social science fields to estimate the effect of programs and interventions. Even when employing experimental data, assessing the impact of a treatment is often complicated by the presence of sample selection (outcomes are only observed for a selected group) and noncompliance (some treatment group individuals do not receive the treatment while some control individuals do). We address both of these identification problems simultaneously and derive nonparametric bounds for average treatment effects within a principal stratification framework. We employ these bounds to empirically assess the wage effects of Job Corps (JC), the most comprehensive and largest federally-funded job training program for disadvantaged youth in the United States. Our results strongly suggest positive average effects of JC on wages for individuals who comply with their treatment assignment and would be employed whether or not they enrolled in JC (the “always-employed compliers”). Under relatively weak monotonicity and mean dominance assumptions, we find that this average effect is between 5.7 and 13.9 percent four years after randomization, and between 7.7 and 17.5 percent for Non-Hispanics. Our results are consistent with larger effects of JC on wages than those found without adjusting for noncompliance.

NBER Working Paper, May 2015
Abstract:
Disability rolls have escalated in developed nations over the last 40 years. The UK, however, stands out because the numbers on these benefits stopped rising when a welfare reform was introduced that integrated disability benefits with unemployment insurance (UI). This policy reform improved job information and sharpened bureaucratic incentives to find jobs for the disabled (relative to those on UI). We exploit the fact that policy was rolled-out quasi-randomly across geographical areas. In the long-run the policy improved the outflows from disability benefits by 6% and had an (insignificant) 1% increase in unemployment outflows. This is consistent with a model where information helps both groups, but bureaucrats were given incentives to shift effort towards helping the disabled find jobs and away from helping the unemployed. Interestingly, in the short-run the policy had a negative impact for both groups, suggesting important disruption effects. We estimate that it takes about six years for the estimated benefits of the reform to exceed its costs, which is beyond the time horizon of most policy-makers.
