Democracy Doesn't Always Happen Over Night: Regime Change in Stages and Economic Growth (2024)
Journal Article

How substantial are the economic benefits from democratic regime change? We argue that democratisation is often not a discrete event but a two-stage process: autocracies enter into 'episodes' of political liberalisation which eventually culminate in...

Climate change and economic prosperity: Evidence from a flexible damage function (2024)
Journal Article

The damage function used to assess the economic impact of secular changes in temperature is one of the most speculative components of integrated assessment models of climate change. Existing work informing this debate is based on pooled empirical mod... Read More about Climate change and economic prosperity: Evidence from a flexible damage function.

Gender Differences in Reference Letters: Evidence from the Economics Job Market (2023)
Journal Article

Academia, and economics in particular, faces increased scrutiny because of gender imbalance. This paper studies the job market for entry-level faculty positions. We employ machine learning methods to analyze gendered patterns in the text of 12,000 re... Read More about Gender Differences in Reference Letters: Evidence from the Economics Job Market.

Democracy, growth, heterogeneity, and robustness (2022)
Journal Article

I motivate and empirically investigate differential long-run growth effects of democratisation across countries. While the existing literature recognises the potential for such heterogeneity, empirical implementations to date unanimously assume a com...

Commodity prices and banking crises (2021)
Journal Article

Commodity prices are one of the most important drivers of output fluctuations in developing countries. We show that a major channel through which commodity price movements can affect the real economy is through their effect on banks' balance sheets a...

Estimating and testing the multicountry endogenous growth model (2020)
Journal Article

© 2020 Elsevier B.V. We estimate Cobb-Douglas production functions that parameterize unobserved total factor productivity as a global technology process interacted with country-specific absorptive capacities. In contrast to the existing literature we... Read More about Estimating and testing the multicountry endogenous growth model.

The Magnitude of the Task Ahead: Macro Implications of Heterogeneous Technology (2019)
Journal Article

The empirical growth literature is dominated by accounting and regression methods which assume common production technology across countries. Our empirical model relaxes this assumption and further allows unobservable determinants of output (Total Fa...

Nonlinearities in the relationship between debt and growth: (no) evidence from over two centuries (2017)
Journal Article

I revisit the popular concern over a nonlinearity or threshold in the relationship between public debt and growth employing long time series data from up to 27 countries. My empirical approach recognises that standard time series arguments for long-r... Read More about Nonlinearities in the relationship between debt and growth: (no) evidence from over two centuries.

What can explain the Chinese patent explosion? (2016)
Journal Article

We analyse the ‘explosion’ of patent filings by Chinese residents both domestically and in the United States during the early 2000s, employing a unique dataset of 374,000 firms matching patent applications to manufacturing census data. Our analysis r... Read More about What can explain the Chinese patent explosion?.

The heterogeneous effect of software patents on expected returns: evidence from India (2016)
Journal Article

We contribute to the literature on the role of patenting for economic development by analyzing the impact of patent protection for software in India. We find that a proposed broadening of patent eligibility to include software in 2004 had a large pos...

The effect of agricultural technology on the speed of development (2016)
Journal Article

We examine heterogeneity in the elasticity of agricultural output with respect to labor. Employing panel data from 128 countries over a forty year period we find distinct heterogeneity in the elasticity of agricultural output with respect to labor. T...

From one to many central plans: drug advertising inspections and intra-national protectionism in China (2015)
Journal Article

This paper provides the first micro-level evidence for the existence and patterns of intra-national protectionism in China. We demonstrate that drug advertising inspections are used by provincial governments to discriminate against firms from outside... Read More about From one to many central plans: drug advertising inspections and intra-national protectionism in China.

Public debt and growth: heterogeneity and non-linearity (2015)
Journal Article

We study the long-run relationship between public debt and growth in a large panel of countries. Our analysis builds on theoretical arguments and data considerations in modelling the debt-growth relationship as heterogeneous across countries. We inve...

No mangoes in the tundra: Spatial heterogeneity in agricultural productivity analysis (2013)
Journal Article

In line with the wider macro productivity literature existing studies of agricultural production largely neglect technology heterogeneity, variable time-series properties and the potential for heterogeneous but correlated total factor productivity (T...

Do spillovers matter when estimating private returns to R&D? (2013)
Journal Article

A large body of literature estimates private returns to R&D adopting the Griliches knowledge production framework, which ignores the potential impact of spillovers on consistent estimation. Using a panel of twelve manufacturing industries across ten... Read More about Do spillovers matter when estimating private returns to R&D?.

Structural change and cross-country growth empirics (2012)
Journal Article

One of the most striking features of economic growth is the process of structural change whereby the share of agriculture in GDP decreases as countries develop. The cross-country growth literature typically estimates an aggregate homogeneous producti... Read More about Structural change and cross-country growth empirics.

Estimating panel time-series models with heterogeneous slopes (2012)
Journal Article

This article introduces a new Stata command, xtmg, that implementsthree panel time-series estimators, allowing for heterogeneous slope coefficients across group members: the Pesaran and Smith (1995, Journal of Econometrics 68: 79-113) mean group esti...

Econometrics for grumblers: A new look at the literature on cross-country growth empirics (2011)
Journal Article

Abstract Since the seminal contribution of N. Gregory Mankiw, David Romer and David N. Weil in 1992 the growth empirics literature has used increasingly sophisticated methods to select relevant growth determinants in estimating cross-section growth r...
