Intensive Margin

This paper develops and estimates an equilibrium model where heterogeneous firms can exploit two margins of informality: (i) not register their business, the extensive margin; and (ii) hire workers “off the books,” the intensive margin. The model encompasses the main competing frameworks for understanding informality and provides a natural setting to infer their empirical relevance. The counterfactual analysis shows that once the intensive margin is accounted for, firm and labor informality need not move in the same direction as a result of policy changes. Lower informality can be, but is not necessarily associated with higher output, TFP, or welfare. (JEL D22, E26, H26, J46, O14, O17)

This chapter explores the patterns of adoption and use of original and new-to-market product innovations. Three levels of diffusion are identified: (i) the spreading of first use across countries (the extensive margin); (ii) the spreading of first use across users within countries (the intensive margin); and (iii) increasing intensity of use by adopters (firms or households). The principal finding is that diffusion often takes a considerable period of time, both across and within countries. Movement on the intensive margin continues for many years after diffusion on the extensive margin is completed. Intra-firm or household diffusion is also time-intensive, differs by industry sector, country, and technology, and continues even after inter-firm or household diffusion is complete. In addition, the diffusion of the production of product innovations may eventually mean that countries that were early producers are eventually replaced by countries that were late producers.

Economic Circumstance

Two margins of political party life in Canada since Confederation (1867) are analyzed—the extensive margin involving entry and exit (together with party turnover or churning) and the intensive margin determining survival length. The results confirm many hypotheses advanced to explain entry and exit—the importance of social and religious cleavage, election institutions, and economic circumstance. More novel are the findings that public election funding and periods with larger immigration flows have reinforced established parties at the expense of entrants and smaller sized parties. The intensive margin uses a discrete hazard model with discrete finite mixtures to confirm the Duverger-type presence of two distinct long-lived political parties surrounded by a fringe of smaller parties. Both parametric and semi-parametric models concur in finding that public funding and higher immigration flows are as successful in extending the life of established parties as in discouraging entry and exit.

Reduce Risk

During a health pandemic health workers have to balance two competing objectives: their own welfare vs. that of their patients. Intuitively, attending to sick patients during a pandemic poses risks to health workers because some of these patients could be infected. One way to reduce risk is by reducing contact with patients. These changes could be on the extensive margin, e.g., seeing fewer patients; or, more insidiously, on the intensive margin, by reducing the duration/intensity of contact. This paper studies risk avoidance behavior during the Covid-19 pandemic and examines implications for patient welfare. Using primary data on thousands of patient-provider interactions between January 2019 and October 2020 in Nigeria, I present evidence of risk compensation by health workers along the intensive margin. For example, the probability that a patient receives a physical examination has dropped by about a third. I find suggestive evidence of negative effects on health outcomes.

Studies on the effect of marijuana on domestic violence often suffer from endogeneity issues. To examine the effect of marijuana decriminalization and medical marijuana legalization on serious domestic assaults, we conducted a difference-in-differences analysis on a panel dataset on NIBRS-reported assaults in 24 states over the 12 years between 2005 and 2016. Assaults disaggregated according to situation and extent of injury were employed as dependent variables. We found that while the total number of assaults did not change, decriminalization reduced domestic assaults involving serious injuries by 18%. From a harm reduction perspective, these results suggest that while the extensive margin of violence did not change, the intensive margin measured by the seriousness of assaults were substantially affected by decriminalization. This result may be partially explained by reductions in offender alcohol intoxication and weapon-involved assault.

Employment at a multinational enterprise (MNE) responds to wages at the extensive margin, when an MNE enters a foreign location, and at the intensive margin, when an MNE operates existing affiliates. We present an MNE model and conditions for parametric and nonparametric identification. Prior studies rarely found wages to affect MNE employment. Our integrated approach documents salient labor substitution for German manufacturing MNEs and removes bias. In Central and Eastern Europe, most employment responds at the extensive margin, while in Western Europe the extensive margin accounts for around two-thirds of employment shifts. At distant locations, MNEs respond to wages only at the extensive margin. (JEL F23, J23, J31, R32)

AbstractThis paper analyzes the determinants of Cognac brandy exports using a unique database on Cognac shipments to more than 140 destinations between 1996 and 2013. We use this database to construct descriptive statistics concerning the evolution of Cognac exports during this period. We also construct a database of protectionist policies that affect worldwide Cognac exports. We analyze the determinants of Cognac exports and base our empirical strategy on Heckman's (1979) procedure. We estimate successively the impact of geographical, demand and policy factors on the extensive margin of trade and the intensive margin of trade. We also control for the possibility of an endogeneity bias on the probability of trade. We show that i) as with other luxury products, the elasticity of Cognac exports to distance is negative, significant, and relatively small, while the elasticity to gross domestic product (GDP) is positive, significant, and relatively large; and ii) average customs duties do not have a significant impact on the intensive margin but significantly and positively affect the probability of trade. We discuss this last result and correct the endogeneity bias using tax revenues of importing countries in percentage of GDP as an instrument. (JEL Classifications: F10, F14)

The Impact

ABSTRACT The choice of exchange rate regime is the most relevant decision in the economic world that has to be faced by the economic authority until now. Exchange rate regime that is applied by one country become a controversial debate after the Asia’s crisis in the year 1997-1998, especially for developing countries and emerging economies in Asia. The purpose of this research is to see the impact of export diversification, intensive margin and extensive margin to the choice of the exchange rate regime in nine emerging and developing countries in Asia 1991-2014.This research uses the panel logistic regression model to analyze the two model that are used in the research; they are: model 1 (the impact of export diversification to the exchange rate regime),and model 2 (the impact of extensive margin and intensive margin to the exchange rate regime. To avoid and to lessen the chances of endogeneity problem therefore, all of the independent variables and the control variable must be lagged in one period.The results of the regression shows that export diversification have a significant positive impact on the exchange rate regime. When export diversification is decomposed into intensive margin and extensive margins, the result shows that the extensive margins also have a significant positive impact towards the exchange rate regime, while the intensive margin does not show any significant impact towards the exchange rate regime choice. Keywords: exchange rate regime, export diversification, intensive margin, extensive margin, emerging and developing countries in Asia.

Credit Market Frictions

Abstract A common prediction of macroeconomic models of credit market frictions is that the tightness of financial constraints is countercyclical. Theory suggests a negative collateralizability premium; that is, capital that can be used as collateral to relax financial constraints insures against aggregate shocks and commands a lower risk compensation compared with noncollateralizable assets. We show that a long-short portfolio constructed using a novel measure of asset collateralizability generates an average excess return of around 8% per year. We develop a general equilibrium model with heterogeneous firms and financial constraints to quantitatively account for the collateralizability premium.
