Abstract We study how financial reforms affect the extent of consumption smoothing in a dynamic stochastic general equilibrium model of an emerging economy. Consistent with the empirical literature and reform efforts in South Korea and South Africa, we emphasize the relation between consumer credit and durable purchases, and model reforms as the relaxation of the collateral constraint on lower income households. We find that the relaxation of the collateral constraint accounts for a substantial share of the decline in consumption smoothing experienced in South Korea and South Africa.

Abstract I develop an extension of a canonical epidemiology model in which the policy in place determines the probability of transmission of an epidemic disease during economic and social interaction. I use the model to evaluate the effects of isolating symptomatic individuals, of increasing social distancing and of tests such as polymerase chain reaction – PCR – or Rapid Diagnostic Test that discriminate between currently infected agents, and its combination with a serology test like Neutralization Assay that is able to discriminate between immune and vulnerable healthy individuals, together with the role of enforcement to prevent interactions involving infected but asymptomatic agents. I find that isolating symptomatic individuals has a large effect at delaying and reducing the pick of infections. The combination of this policy with a PCR test is likely to represents only a negligible improvement in the absence of enforcement, whereas with full enforcement there is an additional delaying and reduction in the pick of infections. Social distancing alone cannot achieve similar effects without incurring in enormous output losses. I explore the combined effect of social distancing at early stages of the epidemic with a following period of tests and find that the best outcome is obtained with a light reduction of human interaction for about three months together with a subsequent test of the population over 40 days.

Abstract The standard models with incomplete markets (e.g. Aiyagari) have difficulty justifying the current income tax rates as an optimal or political equilibrium outcome. Given the highly skewed income distribution, the majority of the population would be in favor of raising taxes to a much higher level. We show that incorporating (i) the ex-ante heterogeneity of earnings and (ii) income-dependent voting behavior helps us to reconcile the large gap between the model and data.

Abstract We study the interplay between the decision of firms to innovate and human capital. Based on a dynamic evolutionary model, we show that in the presence of a high stock of human capital, an advanced economy can remain caught in an “innovation trap”. Following the literature on endogenous growth, R&D investments and human capital are modeled as strategic complements. Skilled workers increase productivity and enjoy a wage premium if they are employed in the R&D sector, while they receive the same wage as unskilled workers if they are employed in the production sector. We model the evolutionary dynamics of the share of innovative firms and human capital to determine the conditions under which an economy converges to a high, low or mixed state of innovation.

Abstract This paper explores the macroeconomic impact of social unrest, using a novel index based on news reports. It shows that unrest has an adverse effect on economic activity, with GDP remaining on average 0.2 percent below the pre-unrest baseline six quarters after a one-standard deviation increase in the unrest index. Moreover, results are robust to instrumenting via regional unrest to address potential endogeneity concerns. Unrest “events”, captured by a large change in the unrest index, result in a more pronounced decline in GDP—a 1 percent reduction six quarters after the event—but impacts differ by type of event. The adverse impact of unrest on activity is mainly associated with sharp contractions in manufacturing and services, and consumption. However, it can be mitigated by strong institutions and by a country’s policy space (such as fiscal space and exchange rate flexibility).

Abstract We develop an endogenous growth model in which long-run growth is driven by three engines: private abatement R&D, expanding-variety R&D, and capital accumulation. We show that an environmental tax activates private abatement by directing researchers from the variety R&D sector to the abatement R&D sector, which helps the economy avoid the environmental disaster. Our results also show that the effect of the environmental tax on long-run growth is uncertain, depending mainly on the relative productivity between the two R&D sectors. If the abatement R&D sector is sufficiently productive, increasing the environmental tax will enhance the balanced output growth rate and social welfare.

Abstract The UK historical monetary policy experience is rich of institutional changes, but it remains unclear which of these many events dominated the policy actions and what timing characterised the inception of different policy regimes. We develop a new empirical approach to answer these questions and we identify in particular the historical institutional events that effectively translated into a shift of the systematic actions of the UK monetary authorities. We find that not all institutional events triggered a contemporaneous change in the actual policy conduct, although a coherent evolution in phases is evident since 1978, when a significant monetary policy rule emerges. These occasional but not sporadic regime changes explain a considerable share of the movements in the official interest rate, as well as an overstatement of the importance of policy inertia.

Abstract How long is the long run in the relationship between money growth and inflation? How important are high inflation episodes for the unit slope finding in the quantity theory of money? To answer these questions, we study the relationship between excess money growth and inflation over time and across frequencies using annual data from 1870 to 2013 for 16 developed countries. Wavelet-based exploratory analysis shows the existence of a close stable relationship between excess money growth and inflation only over long time horizons, i.e. periods greater than 16–24 years, with money growth mostly leading. When we investigate the sensitivity of the unit slope finding to inflation episodes using a “time-frequency-based” panel data approach, we find that low-frequency regression coefficients estimated over variable-length subsamples are largely affected by high inflation episodes occurring in the 1910s, the 1940s, and the 1970s. Taken together, our results suggest that inflationary upsurges affect regression coefficients, but not the closeness of the long-run relationship. This reconciles the validity of the quantity theory of money with the current disinterest of monetary policymaking in money growth.

Abstract We describe and numerically simulate the aggregate and distributional properties of an endogenous growth model with an infrastructure externality which is subject to relative congestion. We show that the congested externality induces higher growth, greater inequality, labor/leisure trade-off ambiguities and an ineffective capital income tax for the government to achieve long-term redistribution goals. We demonstrate the economic implications of congestions in production and consumption externalities on the public to private capital ratio, growth and income distribution. Finally, we discuss alternative tax options for promoting inclusive growth.
