This paper investigates the global economic spillovers emanating from G20 emerging markets (G20-EMs), with a particular emphasis on the comparative influence of China. Employing a Bayesian Global Vector Autoregression (GVAR) model, we assess the impacts of both demand-side and supply-side shocks across 63 countries, capturing the nuanced dynamics of global economic interactions. Our findings reveal that China's contribution to global economic spillovers significantly overshadows that of other G20-EMs. Specifically, China's domestic shocks have significantly larger and more pervasive spillover effects on global GDP, inflation and commodity prices compared to shocks from other G20-EMs. In contrast, spillovers from other G20-EMs are more regionally contained with modest global impacts. The study underscores China's outsized role in shaping global economic dynamics and the limited capacity of other G20-EMs to mitigate any potential negative implications from China's economic slowdown in the near term.

European countries are increasingly turning to industrial policy to address the challenge of geopolitical fragmentation, enhance productivity, and accelerate the green transition. Well-targeted industrial policy has the potential to correct market failures and support production efficiency by exploiting scale effects and internalizing knowledge externalities. But even the most carefully designed unilateral industrial policies risk generating negative production externalities in other countries, and, under certain conditions, may not even be welfare-enhancing for the implementing country. The reason is that negative externalities of unilateral industrial policy can drive European and international production patterns away from underlying comparative advantages, create regional or global over-supply, and result in changes in terms of trade that reduce domestic welfare. This suggests significant benefits from coordination. Structural modeling and case studies show that a coordinated approach within the European Union and with international trading partners on a narrowly defined and carefully designed set of industrial policies could unlock untapped benefits. Closer European integration would facilitate the adjustment of firms and workers to coordinated and well-targeted industrial policies and amplify their benefits.

This paper establishes supply and demand elasticities for a broad set of commodities based on a consistent dataset and identification methodology. We apply granular IV methods to a new cross-country panel dataset of commodity production and consumption from 1960-2021. The results indicate that commodity demand and supply are typically price inelastic. Demand and supply tend to be the most inelastic for minerals, whereas they are most elastic for agricultural commodities. The elasticities of energy commodities fall somewhere in between. Supply and demand become more elastic at longer time horizons for mineral and energy commodities, but not for most agricultural commodities.

We provide systematic evidence on cartels’ characteristics, using novel data on cases investigated by the French Competition Authority. These practices are widely spread across sectors and cartel members are typically among the top firms in their industries. In a model with heterogeneous firms and collusion, cartels amplify misallocation by charging supracompetitive markups. Breaking down French cartels would increase aggregate productivity by 2%, welfare by 3.5%, bringing the economy 37% closer to the efficient frontier. These numbers shed light on the aggregate importance of collusion.

Using business registry data from China, we show that internal capital markets in business groups can propagate corporate shareholders’ credit supply shocks to their subsidiaries. An average of 16.7% local bank credit growth where corporate shareholders are located would increase subsidiaries investment by 1% of their tangible fixed asset value, which accounts for 71% (7%) of the median (average) investment rate among these firms. We argue that equity exchanges is one channel through which corporate shareholders transmit bank credit supply shocks to the subsidiaries and provide empirical evidence to support the channel.

We study the impact of bank credit on firm productivity. We exploit a matched firm-bank database covering all the credit relationships of Italian corporations, together with a natural experiment, to measure idiosyncratic supply-side shocks to credit availability and to estimate a production model augmented with financial frictions. We find that a contraction in credit supply causes a reduction of firm TFP growth and also harms IT-adoption, innovation, exporting, and adoption of superior management practices, while a credit expansion has limited impact. Quantitatively, the credit contraction between 2007 and 2009 accounts for about a quarter of observed the decline in TFP.

We revisit the conventional view that output fluctuates around a stable trend by analyzing professional long-term forecasts for 38 advanced and emerging market economies. If transitory deviations around a trend dominate output fluctuations, then forecasters should not change their long-term output level forecasts following an unexpected change in current period output. By contrast, an analysis of Consensus Economics forecasts since 1989 suggest that output forecasts are super-persistent—an unexpected 1 percent upward revision in current period output typically translates into a revision of ten year-ahead forecasted output by about 2 percent in both advanced and emerging markets. Drawing upon evidence from the behavior of forecast errors, the persistence of actual output is typically weaker than forecasters expect, but still consistent with output shocks normally having large and permanent level effects.

We examine the role of cross-border input linkages in governing how international relative price changes influence demand for domestic value added. We define a novel value-added real effective exchange rate (REER), which aggregates bilateral value-added price changes, and link this REER to demand for value added. Input linkages enable countries to gain competitiveness following depreciations by supply chain partners, and hence counterbalance beggar-thy-neighbor effects. Cross-country differences in input linkages also imply that the elasticity of demand for value added is country specific. Using global input-output data, we demonstrate these conceptual insights are quantitatively important and compute historical value-added REERs.

This paper develops a model featuring both a macroeconomic and a financial friction that speaks to the interaction between monetary and macro-prudential policies. There are two main results. First, real interest rate rigidities in a monopolistic banking system have an asymmetric impact on financial stability: they increase the probability of a financial crisis (relative to the case of flexible interest rate) in response to contractionary shocks to the economy, while they act as automatic macro-prudential stabilizers in response to expansionary shocks. Second, when the interest rate is the only available policy instrument, a monetary authority subject to the same constraints as private agents cannot always achieve a (constrained) efficient allocation and faces a trade-off between macroeconomic and financial stability in response to contractionary shocks. An implication of our analysis is that the weak link in the U.S. policy framework in the run up to the Global Recession was not excessively lax monetary policy after 2002, but rather the absence of an effective regulatory framework aimed at preserving financial stability.

The December 2015 IMF Research Bulletin features a sampling of key research from the IMF. The Research Summaries in this issue look at “The Impact of Deflation and Lowflation on Fiscal Aggregates (Nicolas End, Sampawende J.-A. Tapsoba, Gilbert Terrier, and Renaud Duplay); and “Oil Exporters at the Crossroads: It Is High Time to Diversify” (Reda Cherif and Fuad Hasanov). Mahvash Saeed Qureshi provides an overview of the fifth Lindau Meeting in Economics in “Meeting the Nobel Giants.” In the Q&A column on “Seven Questions on Financial Frictions and the Sources of the Business Cycle, Marzie Taheri Sanjani looks at the driving forces of the business cycle and macroeconomic models. The top-viewed articles in 2014 from the IMF Economic Review are highlighted, along with recent IMF Working Papers, Staff Discussion Notes, and IMF publications.
