The Unassuming Economist

From a paper by Ullrich Heilemann and Roland Schuhr:

“Okun’s misery index (MI), the sum of unemployment rate and inflation rate, is a popular measure of the state of the economy and thus of (macro) ” Economic Discomfort” as well as of government per-formance. We calculate the MI and some augmentations for Germany (until 1990: West Germany) for the period 1951–2021 and test them against a survey-based indicator of government performance (“ZDF-Politbarometer-Index”). The results support Okun’s choice of variables, but reject its augmenta-tion by the growth rate and the deficit ratio. Just as importantly, the effect of unemployment is almost twice as large as that of inflation, and both change considerably over time, as stability tests show. In assessing the performance of governments, MI rankings differ from those of their augmentations. Since the mid-1970s, however, the differences are limited. Barro’s Misery Index, a comparative ap-proach to assessing governments that is an alternative to MI, reaches opposite judgments than MI, but lacks empirical support. The implications for policymakers are both sobering and reassuring: as policy simulations and implied Phillips type trade-offs reveal, the sensitivity of MIs to macroeconomic policy is very low. This may not only hold for Germany given similar international evidence on MIs. The fact that the MI covers the two main macroeconomic objectives, is based on the latest official data, easy to calculate and internationally comparable makes Okun’s Misery Index a useful indicator of Economic Discomfort for Germany as well.”

From a paper by Nicolò Fraccaroli, Vincent Arel-Bundock, and Mark Blyth:

“The 2021 debate over the causes of inflation was dominated by contrasting narratives around the drivers of, and solutions to, rising prices. But how these ideas did or did not penetrate central banks, the politically independent institutions responsible for keeping prices stable, remains unclear. In this paper we investigate how the Bank of England, European Central Bank, and Federal Reserve discussed and deployed specific inflation narratives over time in their attempts to diagnose and treat the inflation of the period. We focus on four narratives that identify the main drivers of inflation in (1) excessive public spending, (2) higher wages in the labour market than warranted by productivity, (3) supply side disruptions to critical markets such as energy, and (4) corporate profit margin expansion. We use a large language model to tag central banks’ speeches with relevant narratives at sentence level, which allows us to quantify how much each central bank discussed each narrative. The results shed new light on how these three central banks interfaced with the recent debate around inflation.”

From a paper by Jordan Kjosevski:

“This study examines the impact of venture capital (VC) investments in artificial intelligence (AI) on unemployment rates across 27 EU member states, distinguishing between old and new EU countries. Utilizing annual data from 2012 to 2023, we explore whether AI investments significantly influence unemployment and how these effects vary between advanced economies and those still developing their digital infrastructure. Employing the two-step system Generalized Method of Moments (GMM), we effectively address endogeneity and the dynamic nature of unemployment, making this method well-suited for our panel dataset covering 27 countries over 12 years. Our findings reveal that AI investments correlate with higher unemployment in old EU countries while positively impacting job creation in new EU member states. Based on these results, we recommend targeted policies to enhance AI adoption, improve digital infrastructure, and promote workforce training, particularly in new member states, to optimize the benefits of AI investments and mitigate potential job displacement.”

From a paper by Pietro Bomprezzi, Silvia Marchesi, and Rima Turk-Ariss:

“This paper investigates the dynamic aggregate response of firm investments to the approval of an IMF arrangement, distinguishing between General Resource Account (GRA) and Poverty Reduction and Growth Trust (PRGT). Using a stacked difference-in-differences estimator and leveraging firm-level characteristics, we find that firms relying more on external finance, those more exposed to uncertainty, or those with domestic ownership tend to increase investments significantly following a GRA agreement. In contrast, the effect is much more limited in the case of PRGT financed programs. The results contribute to the growing literature on the channels through which IMF programs influence the real economy, offering nuanced insights into how these interventions shape private sector dynamics and broader economic development.”

From a paper by Kirsten Sehnbruch, Rafael Carranza Navarrete, and Dante Contreras Guajardo:

“One of the most complex policy issues that developing countries will face as a result of the employment crisis caused by the Covid crisis is the question of how they can better protect the unemployed. However, the analysis of unemployment insurance (UI) in developing economies with large informal sectors is in its infancy, with few papers providing solid empirical evidence. This paper therefore makes several contributions: first, it applies Chetty’s 2008 landmark work on UI to a transition economy (Chile) and shows that the moral hazard effects expected by policy makers, who designed the system are minimal, while liquidity effects were entirely neglected. Second, it demonstrates that it is not enough merely to quantify effects such as moral hazard, but to understand their causes as unemployment generated by moral hazard or liquidity constraints has different welfare implications and should therefore result in different policies. By means of an RDD, this paper analyses the Chilean UI system using a large sample of administrative data, which allows for an extremely precise analysis of how the system works, thus providing invaluable empirical lessons for other countries.”
