Abstract:
Adjustment costs are a central bottleneck of the real-world economic transition essential for achieving the sizeable reduction of greenhouse gas (GHG) emissions set out by policy makers. Could these costs derail the transition process to green growth, and if so, how should policy makers take this into account? I study this issue using the model of directed technical change in Acemoglu, Aghion, Bursztyn, and Hemous (2012), AABH, augmented by a friction on the choice of scientists developing better technologies. My results show that such frictions, even minor, materially affect the outcome. In particular, the risk of reaching an environmental disaster is higher than in the baseline AABH model. Fortunately, policy can address the problem. Specifically, a higher carbon tax ensures a disaster-free transition. In this case, the re-allocation of research activity to the clean sector happens over a longer but more realistic time horizon, namely around 15 instead of 5 years. An important policy implication is that optimal policies do not act over a substantially longer time horizon but must be more aggressive today in order to be effective. In turn, this implies that what may appear as a policy failure in the short-run | a slow transition albeit aggressive policy | actually re ects the efficient policy response to existing frictions in the economy. Furthermore, the risk of getting environmental policy wrong is highly asymmetric and `robust policy' implies erring on the side of stringency. Details

42. Sorting, Matching and Economic Complexity

Abstract:
Assignment models in trade predict that countries with higher productivity levels are assortatively matched to industries that make better use of these higher levels. Here, we assume that the driver of productivity differences is the differential distribution of factors among countries. Utilizing such a structure, we define and estimate the average factor level (AFL) for countries and products using only the information about the production patterns. Interestingly, our estimates coincide with the complexity variables of (Hidalgo and Hausmann, 2009), providing an underlying economic rationale. We show that AFL is highly correlated with country-level characteristics and predictive of future economic growth.

43. National Development Delivers: And How! And How?

Abstract:
Core dual ideas of early development economics and practice were that (a) national development was a four-fold transformation of countries towards: (i) a more productive economy, (ii) a more responsive state, (iii) more capable administration, and (iv) a shared identity and equal treatment of citizens and (b) this four-fold transformation of national development would lead to higher levels of human wellbeing. The second idea is strikingly correct: development delivers. National development is empirically necessary for high wellbeing (no country with low levels of national development has high human wellbeing) and also empirically sufficient (no country with high national development has low levels of human wellbeing). Three measures of national development: productive economy, capable administration, and responsive state, explain (essentially) all of the observed variation in an omnibus indicator of wellbeing, the Social Progress Index, which is based on 58 distinct non-economic indicators. How national development delivers on wellbeing varies, in three ways. One, economic growth is much more important for achieving wellbeing at low versus high levels of income. Two, economic growth matters more for “basic needs” than for other dimensions of wellbeing (like social inclusiveness or environmental quality). Three, state capability matters more for wellbeing outcomes that depend on public production than on private goods (and for some wellbeing indicators, like physical safety, for which growth doesn’t matter at all). While these findings may seem too common sense to be worth a paper, national development--and particularly economic growth—is, strangely, under severe challenge as an important and legitimate objective of action within the development industry.

44. Thinking Beyond the Pandemic: Monetary Policy Challenges in the Medium- to Long-Term

Center for Social and Economic Research - CASE
Abstract:
The economic characteristics of the COVID-19 crisis differ from those of previous crises. It is a combination of demand- and supply-side constraints which led to the formation of a monetary overhang that will be unfrozen once the pandemic ends. Monetary policy must take this effect into consideration, along with other pro-inflationary factors, in the post-pandemic era. It must also think in advance about how to avoid a policy trap coming from fiscal dominance. This paper is organized as follows: Chapter 2 deals with the economic characteristics of the COVID-19 pandemic and its impact on the effectiveness of the monetary policy response measures undertaken. In Chapter 3, we analyse the monetary policy decisions of the ECB (and other major CBs for comparison) and their effectiveness in achieving the declared policy goals in the short term. Chapter 4 is devoted to an analysis of the policy challenges which may be faced by the ECB and other major CBs once the pandemic emergency comes to its end. Chapter 5 contains a summary and the conclusions of our analysis.

45. Do Higher Public Debt Levels Reduce Economic Growth?

Author:
Philipp Heimberger
Publication Date:

Content Type:
Working Paper
Institution:
The Vienna Institute for International Economic Studies (WIIW)
Abstract:
While the effect of higher public debt levels on economic growth has received much attention, the literature partly points to contradictory results. This paper applies meta-regression methods to 826 estimates from 48 primary studies. The unweighted mean of the reported results suggests: a 10 percentage points increase in public-debt-to-GDP is associated with a decline in annual growth rates by 0.14 percentage points, with a 95% confidence interval from 0.10 to 0.18 percentage points. However, we cannot reject a zero effect after correcting for publication bias. Furthermore, the meta-regression analysis shows that tackling endogeneity between public debt and growth makes estimates lean less towards the negative side. In testing for non-linear effects, our results do not point to a universal public-debt-to-GDP threshold beyond which growth slows: threshold estimates are sensitive to data and econometric choices. These findings imply a lack of evidence of a consistently negative growth effect of higher public-debt-to-GDP.

Abstract:
The global economy remained on track in the first months of 2021, despite surging covid-19 infections and renewed containment measures in many countries. The impact of the pandemic was largely confined to the service sectors. Meanwhile, the pronounced upturn in industrial production and global trade continued until spring, but has started to falter as a result of supply bottlenecks and logistical problems. The tensions in the global economic fabric are reflected not least in sharp price increases for raw materials, intermediate goods and transportation services, which have already contributed to a noticeable rise in consumer prices. Continued highly expansionary monetary policy and considerable fiscal policy stimulus, notably in the United States, but also in the euro zone, are fuelling economic activity this year and next. We expect global output (measured on a purchasing power parity basis) to increase by 6.7 percent in 2021 and by 4.8 percent in 2022, which is still substantially above medium-term trend growth. In view of the high economic momentum and higher inflation risks, we expect the Federal Reserve to start tightening earlier than previously expected. This is associated with the risk of a significant deterioration in financing conditions going forward, particularly for some emerging economies

47. Endogenous Growth, Skill Obsolescence and Optimal Monetary Policy

Working Paper
Institution:
Kiel Institute for the World Economy (IfW)
Abstract:
We analyze Ramsey optimal monetary policy in a New-Keynesian model with search and matching frictions featuring (i) training costs due to skill loss from long-term unemployment and (ii) endogenous growth through learning-by-doing externalities. In a simplified two-period version of the model, the competitive equilibrium is shown to be inefficient due to two externalities: i) firms do not internalize the effects that hiring has on labor productivity through learning-by-doing; ii) firms do not fully internalize the effects that hiring has on future training costs. These externalities lead to inefficient fluctuations, thereby justifying deviations from price stability in response to productivity shocks. In a calibrated version of the full model we show significant deviations from price stability and significant differences between optimal monetary policy and monetary policy that follows a Taylor rule.

48. Horrible Trade-offs in a Pandemic: Lockdowns, Transfers, Fiscal Space, and Compliance

Author:

Abstract:
In this paper, we develop a heterogeneous agent general equilibrium framework to analyze optimal joint policies of a lockdown and transfer payments in times of a pandemic. In our model, the effectiveness of a lockdown in mitigating the pandemic depends on endogenous compliance. A more stringent lockdown deepens the recession which implies that poorer parts of society find it harder to subsist. This reduces their compliance with the lockdown, and may cause deprivation of the very poor, giving rise to an excruciating trade-off between saving lives from the pandemic and from deprivation. Lump-sum transfers help mitigate this trade-off. We identify and discuss key trade-offs involved and provide comparative statics for optimal policy. We show that, ceteris paribus, the optimal lockdown is stricter for more severe pandemics and in richer countries. We then consider a government borrowing constraint and show that limited fiscal space lowers the optimal lockdown and welfare, and increases the aggregate death burden during the pandemic. We finally discuss distributional consequences and the political economy of fighting a pandemic.

Abstract:
This article examines 77 countries with the most significant economic liberalizations since 1970, as measured by changes in the Economic Freedom of the World (EFW) index. Measures of both the speed and comprehensiveness of the reforms are presented. Our empirical evidence suggests that faster reforming nations economically outperformed slower reformers. We do not find evidence that more comprehensive reforms, as opposed to more narrowly targeted reforms, had much of an impact on ensuing economic growth.

50. Growth Models and the Footprint of Transnational Capital

Abstract:
The definition of various growth models is the latest innovation of comparative capitalism (CC) research. Yet, the literature has its weaknesses in explaining the dynamics within and the interdependencies between different growth models. I argue that this weakness stems inter alia from an inadequate conceptualization of transnational corporations (TNCs). I provide empirical evidence on the footprint of international capital in the global economy and outline how including TNCs as a unit of analysis can help us to better understand economic outcomes. This leads to several implications for the growth models literature, which I conclude my argument with.
