JEEA publication by Benedikt Herz ’08 and Thijs van Rens (former BGSE professor)

cover

Benedkit Herz (Economics ’08, GPEFM ’13), has published a paper in the Journal of the European Economic Association. His co-author is former Barcelona GSE Professor Thijs van Rens (now at Warwick).

Paper abstract

We investigate unemployment due to mismatch in the United States over the past three and a half decades. We propose an accounting framework that allows us to estimate the contribution of each of the frictions that generated labor market mismatch. Barriers to job mobility account for the largest part of mismatch unemployment, with a smaller role for barriers to worker mobility. We find little contribution of wage-setting frictions to mismatch.

Backlash: The Unintended Effects of Language Prohibition in US Schools after World War I

Review of Economic Studies publication by Vicky Fouka ’10 (Economics)

The paper Backlash: The Unintended Effects of Language Prohibition in U.S. Schools after World War I by Economics alum Vicky Fouka ’10 has been published in the Review of Economic Studies (REStud).

Her research on the topic was also featured in The Washington Post last year!

Paper abstract

Do forced assimilation policies always succeed in integrating immigrant groups? This paper examines how a specific assimilation policy – language restrictions in elementary school – affects integration and identification with the host country later in life. After World War I, several US states barred the German language from their schools. Affected individuals were less likely to volunteer in WWII and more likely to marry within their ethnic group and to choose decidedly German names for their offspring. Rather than facilitating the assimilation of immigrant children, the policy instigated a backlash, heightening the sense of cultural identity among the minority.

Specific Human Capital and Wait Unemployment

Publication in the Journal of Labor Economics by Benedikt Herz ’08 (Economics)

cover

The main chapter of the PhD dissertation by Benedkit Herz (Economics ’08, GPEFM ’13), “Specific Human Capital and Wait Unemployment,” has been published in the Journal of Labor Economics and is now available online.

Paper abstract

A displaced worker might rationally prefer to wait through a long spell of unemployment instead of seeking employment at a lower wage in a job he is not trained for. I evaluate this trade-off using micro data on displaced workers. To achieve identification, I exploit the fact that the more a worker has invested in occupation-specific human capital, the more costly it is for him to switch occupations and therefore the higher is his incentive to wait. I find that between 9% and 17% of total unemployment in the United States can be attributed to wait unemployment

Sectoral risk-weights and macroprudential policy

Publication in Journal of Banking and Finance by Alex Hodbod (ITFD ’12) and Steffi Huber (Economics ’10, GPEFM ’17)

We have a forthcoming article “Sectoral Risk Weights and Macroprudential Policy” in the Journal of Banking & Finance with our co-author Konstantin Vasilev (Essex).

The authors!

Paper abstract

This paper analyses bank capital requirements in a general equilibrium model by evaluating the implications of different designs of such requirements regarding their impact on the tendency of banks to amplify the business cycle.

figure
Interest rate spreads structure. This figure gives an overview of the different interest rate spreads within the model and the factors that affect them. The asset-specific interest rate spreads determine the borrowing costs of households and firms and hence the quantities of specific loan types in the economy.

We compare the Basel-established Internal Ratings-Based (IRB) approach to risk-weighting assets with an alternative macroprudential approach which sets risk-weights in response to sectoral measures of leverage. The different methods are compared in a crisis scenario, where the crisis originates from the housing market that affects the banking sector and is then transmitted to the wider economy.

figure
Variance decomposition – real consumption during the Great Recession. This variance decomposition shows that the model identifies the productivity shock and the shock to mortgage lending risk to be the main drivers of the crash in real consumption during the Great Recession. In our model, the main channel through which the shock to mortgage risk has a procyclical effect on consumption is through lending and house prices.

We investigate both boom and bust phases of the crisis by simulating an unrealized news shock that leads to a gradual build-up and rapid crash in the economy. Our results suggest that the IRB approach creates procyclicality in regulatory capital requirements and thereby works to amplify both boom and bust phases of the financial cycle. On the other hand, our proposed macroprudential approach to setting risk-weights leads to counter-cyclicality in regulatory capital requirements and thereby attenuates the financial cycle.

figure
Impulse Response Function – Unrealised news shock. Here, we model both the build-up and crash phases of the crisis and use this to examine how different policy approaches perform in handling the boom phase of the cycle. In periods 1-4 agents start with expectations that a housing boom will occur, but at period 4 a shock arrives as this boom does not materialise. At the top of the chart one sees that the policy setup based on the IRB approach (red) generates the biggest macroeconomic consequences from this shock; it is the most procyclical. The macroprudential approach to risk-weighting (in green) is the least procyclical. An unweighted “leverage ratio” approach (blue) is less procyclical than the IRB approach, but more so than our macroprudential approach.

Conclusions in brief

  • We show that IRB risk-weights can induce procyclicality of capital requirements and amplify both boom and bust phases of the business cycle. This is particularly concerning because procyclical risk weights could undermine other macroprudential tools, as these other tools are themselves based on risk-based measures of capital requirements e.g. Counter Cyclical Capital Buffers.
  • Our alternative approach of macroprudential risk weights could induce countercyclicality of capital requirements, which may offer benefits in terms of smoothening financial cycles. Targeting macroprudential intervention on bank risk-weights is likely to be more effective when it is sector-specific. This will alter banks’ incentives in a sensitive way – thereby tending to attenuate sectoral asset booms.
  • The results complement the ongoing debate about the potential merits of a Sectoral Counter Cyclical Capital Buffer, which is ongoing internationally.

Structural Change and the Fertility Transition

Forthcoming paper in Review of Economics and Statistics by Philipp Ager ’08 and Benedikt Herz ’08 (Economics)

Paper abstract

This paper provides new insights on the relationship between structural change and the fertility transition. We exploit the spread of an agricultural pest in the American South in the 1890s as plausibly exogenous variation in agricultural production to establish a causal link between earnings opportunities in agriculture and fertility. Households staying in agriculture reduced fertility because children are a normal good, while households switching to manufacturing reduced fertility because of the higher opportunity costs of raising children. The lower earnings opportunities in agriculture also decreased the value of child labor which increased schooling, consistent with a quantity-quality model of fertility.

Confidence Intervals for Bias and Size Distortion in IV and Local Projections-IV Models

Publication in “Journal of Business & Economic Statistics” by
Gergely Ganics ’12 (with A. Inoue and B. Rossi)

Abstract

In this article, we propose methods to construct confidence intervals for the bias of the two-stage least squares estimator, and the size distortion of the associated Wald test in instrumental variables models with heteroscedasticity and serial correlation. Importantly our framework covers the local projections—instrumental variable model as well. Unlike tests for weak instruments, whose distributions are nonstandard and depend on nuisance parameters that cannot be consistently estimated, the confidence intervals for the strength of identification are straightforward and computationally easy to calculate, as they are obtained from inverting a chi-squared distribution. Furthermore, they provide more information to researchers on instrument strength than the binary decision offered by tests. Monte Carlo simulations show that the confidence intervals have good, albeit conservative, in some cases, small sample coverage. We illustrate the usefulness of the proposed methods in two empirical situations: the estimation of the intertemporal elasticity of substitution in a linearized Euler equation, and government spending multipliers. 

Supplementary materials for this article are available online. The online appendix contains the proofs, further theoretical and Monte Carlo results, and the description of the datasets used in the present article. Replication code is available on the journal’s website.

Measuring horizontal inequity in healthcare utilisation

Publication by Mohammad Habibullah Pulok ’12 (HEP)

My first paper from PhD is out in the European Journal of Health Economics: “Measuring horizontal inequity in healthcare utilisation: a review of methodological developments and debates”

Paper abstract

Equity in healthcare is an overarching goal of many healthcare systems around the world. Empirical studies of equity in healthcare utilisation primarily rely on the horizontal inequity (HI) approach which measures unequal utilisation of healthcare services by socioeconomic status (SES) for equal medical need. The HI method examines, quantifies, and explains inequity which is based on regression analysis, the concentration index, and the decomposition technique. However, this method is not beyond limitations and criticisms, and it has been subject to several methodological challenges in the past decade.

This review presents a summary of the recent developments and debates on various methodological issues and their implications on the assessment of HI in healthcare utilisation. We discuss the key disputes centred on measurement scale of healthcare variables as well as the evolution of the decomposition technique. We also highlight the issues about the choice of variables as the indicator of SES in measuring inequity. This follows a discussion on the application of the longitudinal method and use of administrative data to quantify inequity.

Future research could exploit the potential for health administrative data linked to social data to generate more comprehensive estimates of inequity across the healthcare continuum. This review would be helpful to guide future applied research to examine inequity in healthcare utilisation.

How Destructive is Innovation?

Publication in Econometrica by Daniel Garcia-Macia ’11 (Economics)

Daniel’s paper “How Destructive is Innovation?” (with Chang-Tai Hsieh & Peter Klenow) has been published in Econometrica (September 2019).

The paper has received media attention in NBER Digest, Chicago Booth Review, Financial Times, and Bloomberg.

Paper abstract

Entrants and incumbents can create new products and displace the products of competitors. Incumbents can also improve their existing products. How much of aggregate productivity growth occurs through each of these channels? Using data from the U.S. Longitudinal Business Database on all nonfarm private businesses from 1983 to 2013, we arrive at three main conclusions: First, most growth appears to come from incumbents. We infer this from the modest employment share of entering firms (defined as those less than 5 years old). Second, most growth seems to occur through improvements of existing varieties rather than creation of brand new varieties. Third, own‐product improvements by incumbents appear to be more important than creative destruction. We infer this because the distribution of job creation and destruction has thinner tails than implied by a model with a dominant role for creative destruction.

Small Numbers, Big Concerns: Practices and Organizational Arrangements in Rare Disease Drug Repurposing

Publication by Burcu Kucukkeles ’12 (Economics)

Burcu Kücükkeles (Economics ’12) has published a paper in the Academy of Management Discoveries. In this paper, “Small Numbers, Big Concerns: Practices and Organizational Arrangements in Rare Disease Drug Repurposing,” Burcu and her colleagues looked into the societal challenge of developing drugs for rare diseases (a rare disease is a condition that affects less than 200,000 people in the United States or 1 in 2,000 people in the European Union).

By studying the market and government failures in rare diseases and practices of two nonprofit organizations, Burcu and her colleagues contribute to the Agenda on the Sustainable Development Goals beyond the implications of their study to the management literature.

Burcu is currently a PhD candidate at the Chair of Strategic Management and Innovation, Department of Management, Technology, and Economics, ETH Zurich. Voice readers are welcome to email her for access to the full paper or with any questions about this research: burcuk [ at ] ethz [. ]ch

Paper Abstract

Due to their small market size, many rare diseases lack treatments. While government incentives exist for the development of drugs for rare diseases, these interventions have yielded insufficient progress. Drawing on an in-depth case study of rare diseases therapies, we explore how the practices of two nonprofit organizations allowed them to circumvent the endemic market and government failures involving positive externalities by using generic drug repurposing—i.e., seeking new therapeutic applications for existing generic drugs. Beyond elucidating the potential of generic drug repurposing for those suffering from rare diseases, our discoveries provide important insights into the mutual constitution of organizational arrangements for societal challenges and the practices they host. By showing how organizational arrangements can both reinforce and extend practices such that they enable practitioners to achieve a standard of excellence, our study advances practice theory and research on the comparative efficacy of alternative organizational arrangements for tackling societal challenges.

How do firms adjust to rises in the minimum wage? Survey evidence from Central and Eastern Europe

Publication by Nataša T. Jemec ’09 (Economics) and Ludmila Fadejeva ’11 (Macro)

Nataša Todorović Jemec ’09 (Economics) and Ludmila Fadejeva ’11 (Macroeconomic Policy and Financial Markets) have published a paper in the IZA Journal of Labour Policy, together with a few other colleagues from central banks of new EU member states. The paper, “How do firms adjust to rises in the minimum wage? Survey evidence from Central and Eastern Europe,” studies the transmission channels for rises in the minimum wage using a unique firm-level dataset from eight Central and Eastern European countries.

They wrote the publication within the ECB Wage Dynamics Network (WDN). At the time, Nataša and Ludmila were working at the Central Bank of Slovenia and the Central Bank of Latvia respectively, and they were their banks’ representatives in the WDN. Increase of the minimum wage was a common topic of many new EU members, and they decided to write a paper on that based on the data that they collected through a WDN survey in their countries.

Researchers can use this form to request access to the data of the WDN network which includes many EU countries.

Paper abstract

We study the transmission channels for rises in the minimum wage using a unique firm-level dataset from eight Central and Eastern European countries. Representative samples of firms in each country were asked to evaluate the relevance of a wide range of adjustment channels following specific instances of rises in the minimum wage during the recent post-crisis period. The paper adds to the rest of literature by presenting the reactions of firms as a combination of strategies and evaluates the relative importance of those strategies. Our findings suggest that the most popular adjustment channels are cuts in non-labour costs, rises in product prices, and improvements in productivity. Cuts in employment are less popular and occur mostly through reduced hiring rather than direct layoffs. Our study also provides evidence of potential spillover effects that rises in the minimum wage can have on firms without minimum wage workers.
