This paper studies the spillover of a macroprudential regulation in Spain to the Mexican financial system via Mexican subsidiaries of Spanish banks. The spillover caused a drop in the supply of household credit in Mexico. Municipalities with a higher exposure to Spanish subsidiaries experienced a larger contraction in household credit. These localized contractions caused a drop in macroeconomic activity in the local non-tradable sector. Estimates of the elasticity of loan demand by the non-tradable sector to changes in household credit supply range from 1.2–1.8. These results emphasize cross-border effects of regulations in the presence of global banks.
Loan-loss provisions introduced in Spain in 2012 imposed a significant burden on the balanced sheet of Spanish banks. This regulation was unrelated to the Mexican financial system or the credit conditions of Mexican households. However, Mexican subsidiaries of two large Spanish banks, BBVA and Santander, reduced lending to Mexican households in response to the regulation (Fig. 1).
Mexican municipalities with a higher exposure to Spanish banks (Fig. 2) experienced a larger contraction in lending to households. This drop in lending to households (i.e. a drop in credit supply) was associated with a reduction in lending to the local non-tradable sector driven by a drop in local demand. This shows (1) cross-border effects of a macroprudential regulation on lending and economic activity, and (2) the macroeconomic effects of shocks in lending to households in an emerging economy.
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.
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.
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

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

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.

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.

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”
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.
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.
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.

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.
