Understanding the Great Recession

Mathias Trabandt, Lawrence J. Christiano, Martin S. Eichenbaum
American Economic Journal: Macroeconomics, No. 1, 2015
Abstract
We argue that the vast bulk of movements in aggregate real economic activity during the Great Recession were due to financial frictions. We reach this conclusion by looking through the lens of an estimated New Keynesian model in which firms face moderate degrees of price rigidities, no nominal rigidities in wages, and a binding zero lower bound constraint on the nominal interest rate. Our model does a good job of accounting for the joint behavior of labor and goods markets, as well as inflation, during the Great Recession. According to the model the observed fall in total factor productivity and the rise in the cost of working capital played critical roles in accounting for the small drop in inflation that occurred during the Great Recession.

Isolation and Innovation – Two Contradictory Concepts? Explorative Findings from the German Laser Industry

Wilfried Ehrenfeld, T. Pusch, Muhamed Kudic
IWH Discussion Papers, No. 1, 2015
Abstract
We apply a network perspective and study the emergence of core-periphery (CP) structures in innovation networks to shed some light on the relationship between isolation and innovation. It has been frequently argued that a firm’s location in a densely interconnected network area improves its ability to access information and absorb technological knowledge. This, in turn, enables a firm to generate new products and services at a higher rate compared to less integrated competitors. However, the importance of peripheral positions for innovation processes is still a widely neglected issue in literature. Isolation may provide unique conditions that induce innovations which otherwise may never have been invented. Such innovations have the potential to lay the ground for a firm’s pathway towards the network core, where the industry’s established technological knowledge is assumed to be located. The aim of our paper is twofold. Firstly, we propose a new CP indicator and apply it to analyze the emergence of CP patterns in the German laser industry. We employ publicly funded Research and Development (R&D) cooperation project data over a period of more than two decades. Secondly, we explore the paths on which firms move from isolated positions towards the core (and vice versa). Our exploratory results open up a number of new research questions at the intersection between geography, economics and network research.

EFN Report Winter 2014/15: Economic Outlook for the Euro Area in 2015 and 2016

EFN Reports, No. 1, 2015
Abstract
At the beginning of the year 2015 crude oil is, with little more than 50 dollars per barrel (Brent), about 50% cheaper than in the summer 2014. The oil price hike is a stimulus for the whole world economy, even though the gains of energy users are matched by losses of the suppliers: oil producing countries frequently run high current account surpluses vis-à-vis the rest of the world. It is therefore plausible to assume that, reacting to the redistribution of incomes, the oil user countries will increase their spending by more than what will be lost in spending by producers. Investment activity in the euro area has recently been particularly weak. Remarkably, investment in Greece, Portugal, and Spain, i.e. in countries that had to accept international support during the euro crisis, has strengthened. The setback took place in the so-called core countries, including Germany. Consumption growth was also subdued. Lower oil prices, by increasing real incomes of consumers and lowering production costs for firms, should increase private consumption and, in particular, investment. Moreover, the depreciation of the euro will favour exports. Overall, according to our forecasts, the euro area GDP will grow by 1.3% in 2015 and by 1.6% in 2016. GDP growth is about 0.3 percentage points higher due to the impact of lower oil prices in 2015. However, these forecasts are subject to substantial uncertainty, and we do not see any significant reduction of the unemployment rate during the forecasting horizon. Our inflation forecast for 2015 is 0.3%, with the possibility of a mild deflation not excluded. In 2016 inflation will increase up to 1.1%, still clearly below the 2% ECB’s target. This calls for further monetary expansion, though its effects could be limited in the absence of a complementary fiscal stimulus. The expansionary cyclical policies should be combined with more structural reforms to enhance the competitiveness of the euro area and its growth potential, which in our forecasts remains quite limited. In fact, we expect potential output to grow by only 0.4% both in 2015 and 2016.

Private Equity, Jobs, and Productivity

Steven J. Davis, John Haltiwanger, Kyle Handley, Ron S. Jarmin, Josh Lerner, Javier Miranda
American Economic Review, No. 12, 2014
Abstract
Private equity critics claim that leveraged buyouts bring huge job losses and few gains in operating performance. To evaluate these claims, we construct and analyze a new dataset that covers US buyouts from 1980 to 2005. We track 3,200 target firms and their 150,000 establishments before and after acquisition, comparing to controls defined by industry, size, age, and prior growth. Buyouts lead to modest net job losses but large increases in gross job creation and destruction. Buyouts also bring TFP gains at target firms, mainly through accelerated exit of less productive establishments and greater entry of highly productive ones.

Euro Area External Imbalances and the Burden of Adjustment

Filippo di Mauro, Francesco Pappadà
Journal of International Money and Finance, November 2014
Abstract
The objective of this paper is to explore the consequences of the correction of Euro area trade imbalances on real exchange rates. This analysis requires one additional dimension with respect to the standard Global Imbalances framework à la Obstfeld and Rogoff (2005), since the adjustment takes place within and outside the Euro area. Both types of adjustments are analyzed in a three-country general equilibrium model with a tradable and a non-tradable sectors, and heterogeneous firms built upon Pappadà (2011). ECB (CompNet) data are used to measure the differences in firm size and productivity dispersion across Euro area countries. With respect to the surplus country (Germany), countries running a trade deficit (Spain, Italy) are characterised by a productivity distribution with a lower mean and a less fat right tail. This increases the relative price movement associated with the external adjustment because of the limited role played by the extensive margin. We show that the real exchange rate movements are underestimated when the cross-country differences in terms of productivity distributions are neglected.

Should I Stay or Should I Go? Bank Productivity and Internationalization Decisions

Claudia M. Buch, C. T. Koch, Michael Koetter
Journal of Banking and Finance, No. 42, 2014
Abstract
Differences in firm-level productivity explain international activities of non-financial firms quite well. We test whether differences in bank productivity determine international activities of banks. Based on a dataset that allows tracking banks across countries and across different modes of foreign entry, we model the ordered probability of maintaining a commercial presence abroad and the volume of banks’ international assets empirically. Our research has three main findings. First, more productive banks are more likely to enter foreign markets in increasingly complex modes. Second, more productive banks also hold larger volumes of foreign assets. Third, higher risk aversion renders entry less likely, but it increases the volume of foreign activities conditional upon entry.

EFN Report Autumn 2014: Economic Outlook for the Euro Area in 2014 and 2015

, 2014
Abstract
In autumn 2014, world production continues to be expanding at a moderate rate, a bit faster than at the beginning of the year. A strong upswing of the world economy is, however, not in sight: the US upswing continues but is not probable to gain more pace, and the Chinese economy has to cope with severe problems in the financial and the housing sector. Important conditions for a stronger recovery are in place: the fall in financing costs allows euro area governments to conduct fiscal policies that are, on average, clearly less restrictive than in the years before, and nonfinancial firms benefit from a shrinking burden of interest payments. Interest rates for bank credit in the southern economies are now slowly going down. However, the recovery will stay sluggish as long as firms and households lack confidence in the economic policy of important member states. In fact, economic confidence in the euro area declined somewhat during summer in part due to news on the conflict between Russia and the west, although only about 5% of all exports leaving the euro area go to Russia or Ukraine. Production growth in the euro area slowed down to stagnation in the second quarter, mainly due to a decline in Germany related to a weather effect. Demand in the rest of the euro area continued to slowly expand. In this context, we forecast that the euro area economy will expand by 1.3% in 2015, after 0.9% in 2014. For 2014 and 2015, we do not see any significant reduction of the unemployment rate, because employment dynamics will stay weak due to subdued growth and the still rising participation rate in the euro area. Our inflation forecast for 2014 is 0.5%. In 2015 inflation will also remain subdued, at about 1.1%.

The Role of Entrepreneurship in US Job Creation and Economic Dynamism

Ryan A. Decker, John Haltiwanger, Ron S. Jarmin, Javier Miranda
Journal of Economic Perspectives, No. 3, 2014
Abstract
An optimal pace of business dynamics—encompassing the processes of entry, exit, expansion, and contraction—would balance the benefits of productivity and economic growth against the costs to firms and workers associated with reallocation of productive resources. It is difficult to prescribe what the optimal pace should be, but evidence accumulating from multiple datasets and methodologies suggests that the rate of business startups and the pace of employment dynamism in the US economy has fallen over recent decades and that this downward trend accelerated after 2000. A critical factor in accounting for the decline in business dynamics is a lower rate of business startups and the related decreasing role of dynamic young businesses in the economy. For example, the share of US employment accounted for by young firms has declined by almost 30 percent over the last 30 years. These trends suggest that incentives for entrepreneurs to start new firms in the United States have diminished over time. We do not identify all the factors underlying these trends in this paper but offer some clues based on the empirical patterns for specific sectors and geographic regions.

EFN Report Summer 2014: Economic Outlook for the Euro Area in 2014 and 2015

, 2014
Abstract
World growth disappointed at the beginning of the year, when in the US extremely cold weather caused production to contract, the recovery in the euro area stumbled and the slowdown of the Chinese economy continued. At present, however, confidence indicators and order books point to a moderate pickup of growth in most regions. Prices on markets for energy, real and financial assets have reacted little to recent bad news about rising geopolitical risks in the Middle East and Eastern Europe up to now. A sudden increase of risk aversion or a change of believes among investors could trigger a swift deterioration of financial conditions for the world economy. In the euro area, strong stimuli from abroad are not to be expected and private households continue to keep their real spending about constant. Investment has been expanding since summer 2013, but at a very moderate rate. In this context, our forecast for GDP growth is 1.1% in 2014 and 1.6% in 2015. For 2014 and 2015, we do not see any significant reduction of the unemployment rate, because employment dynamics will stay weak due to subdued growth and the still rising participation rate in the euro area. Our inflation forecast for 2014 is 0.6%. In 2015 inflation will also remain subdued, at about 1.0%. In this context of very low price dynamics, monetary policy keeps the recovery alive: official interest rates around zero and the search for yields on financial markets have depressed yields for government bonds; the fall in financing costs allows euro area governments to conduct fiscal policies that are much less restrictive than in the years before, with tax cuts in Italy, France, and Spain starting this year. Nonfinancial firms benefit from a shrinking burden of interest payments, and the availability of bank loans for small and medium enterprises has improved since 2012 in most countries.

Micro-Based Evidence of EU Competitiveness: The CompNet Database

Filippo di Mauro, et al.
ECB Working Paper, No. 1634, 2014
Abstract
Drawing from confidential firm-level balance sheets in 11 European countries, the paper presents a novel sectoral database of comparable productivity indicators built by members of the Competitiveness Research Network (CompNet) using a newly developed research infrastructure. Beyond aggregate information available from industry statistics of Eurostat or EU KLEMS, the paper provides information on the distribution of firms across several dimensions related to competitiveness, e.g. productivity and size. The database comprises so far 11 countries, with information for 58 sectors over the period 1995-2011. The paper documents the development of the new research infrastructure, describes the database, and shows some preliminary results. Among them, it shows that there is large heterogeneity in terms of firm productivity or size within narrowly defined industries in all countries. Productivity, and above all, size distribution are very skewed across countries, with a thick left-tail of low productive firms. Moreover, firms at both ends of the distribution show very different dynamics in terms of productivity and unit labour costs. Within-sector heterogeneity and productivity dispersion are positively correlated to aggregate productivity given the possibility of reallocating resources from less to more productive firms. To this extent, we show how allocative efficiency varies across countries, and more interestingly, over different periods of time. Finally, we apply the new database to illustrate the importance of productivity dispersion to explain aggregate trade results.
