Strong Financial Literacy could Lead to More Self-employment
The probability that a person is self-employed also depends on how much financial literacy they have. A new study by the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association recently confirmed this correlation.

The Joint Dynamics of Sovereign Ratings and Government Bond Yields
Makram El-Shagi, Gregor von Schweinitz
Abstract
Can a negative shock to sovereign ratings invoke a vicious cycle of increasing government bond yields and further downgrades, ultimately pushing a country toward default? The narratives of public and political discussions, as well as of some widely cited papers, suggest this possibility. In this paper, we will investigate the possible existence of such a vicious cycle. We find no evidence of a bad long-run equilibrium and cannot confirm a negative feedback loop leading into default as a transitory state for all but the very worst ratings.

The German Economy Benefits from Strong Domestic Demand
In 2016, the moderate upswing of the German economy continues. Incomes grow due to the steady expansion in employment, and the fall in energy prices has propped up the purchasing power of private households. As a consequence, private consumption expands healthily; investment in housing is additionally stimulated by very low interest rates. Exports, however, expand only moderately, as the world economy is rather weak. All in all, the IWH forecasts the German GDP to expand by 1.8% in this year and by 1.6% in 2017.

Are Lacking Structural Reforms in the Financial Sector the Underlying Reason for the German Criticism of the ECB?
The major reason for the intense criticism of the European Central Bank’s (ECB’s) low-interest-rate policy may be the lack of structural reforms in the German banking system. The resulting persistent fragmentation increases the banking sector’s vulnerability to the low-interest-rate environment. Hence, parts of the banking sector, due to their strong ties to politicians, appear to have successfully influenced public opinion against the ECB.

Measuring Income Tax Evasion Using Bank Credit: Evidence from Greece
Nikolaos Artavanis, Adair Morse, Margarita Tsoutsoura
Quarterly Journal of Economics,
No. 2,
2016
Abstract
We document that in semiformal economies, banks lend to tax-evading individuals based on the bank’s assessment of the individual’s true income. This observation leads to a novel approach to estimate tax evasion. We use microdata on household credit from a Greek bank and replicate the bank underwriting model to infer the banks estimate of individuals’ true income. We estimate that 43–45% of self-employed income goes unreported and thus untaxed. For 2009, this implies €28.2 billion of unreported income, implying forgone tax revenues of over €11 billion or 30% of the deficit. Our method innovation allows for estimating the industry distribution of tax evasion in settings where uncovering the incidence of hidden cash transactions is difficult using other methods. Primary tax-evading industries are professional services—medicine, law, engineering, education, and media. We conclude with evidence that contemplates the importance of institutions, paper trail, and political willpower for the persistence of tax evasion.

Networks and the Macroeconomy: An Empirical Exploration
Daron Acemoglu, Ufuk Akcigit, William R. Kerr
NBER Macroeconomics Annual,
2015
Abstract
How small shocks are amplified and propagated through the economy to cause sizable fluctuations is at the heart of much macroeconomic research. Potential mechanisms that have been proposed range from investment and capital accumulation responses in real business-cycle models (e.g., Kydland and Prescott 1982) to Keynesian multipliers (e.g., Diamond 1982; Kiyotaki 1988; Blanchard and Kiyotaki 1987; Hall 2009; Christiano, Eichenbaum, and Rebelo 2011); to credit market frictions facing firms, households, or banks (e.g., Bernanke and Gertler 1989; Kiyotaki and Moore 1997; Guerrieri and Lorenzoni 2012; Mian, Rao, and Sufi 2013); to the role of real and nominal rigidities and their interplay (Ball and Romer 1990); and to the consequences of (potentially inappropriate or constrained) monetary policy (e.g., Friedman and Schwartz 1971; Eggertsson and Woodford 2003; Farhi and Werning 2013).

A Review of Empirical Research on the Design and Impact of Regulation in the Banking Sector
Sanja Jakovljević, Hans Degryse, Steven Ongena
Annual Review of Financial Economics,
2015
Abstract
We review existing empirical research on the design and impact of regulation in the banking sector. The impact of each individual piece of regulation may inexorably depend on the set of regulations already in place, the characteristics of the banks involved (from their size or ownership structure to operational idiosyncrasies in terms of capitalization levels or risk-taking behavior), and the institutional development of the country where the regulation is introduced. This complexity is challenging for the econometrician, who relies either on single-country data to identify challenges for regulation or on cross-country data to assess the overall effects of regulation. It is also troubling for the policy maker, who has to optimally design regulation to avoid any unintended consequences, especially those that vary over the credit cycle such as the currently developing macroprudential frameworks.

Electoral Credit Supply Cycles Among German Savings Banks
Reint E. Gropp, Vahid Saadi
IWH Online,
No. 11,
2015
Abstract
In this note we document political lending cycles for German savings banks. We find that savings banks on average increase supply of commercial loans by €7.6 million in the year of a local election in their respective county or municipality (Kommunalwahl). For all savings banks combined this amounts to €3.4 billion (0.4% of total credit supply in Germany in a complete electoral cycle) more credit in election years. Credit growth at savings banks increases by 0.7 percentage points, which corresponds to a 40% increase relative to non-election years. Consistent with this result, we also find that the performance of the savings banks follows the same electoral cycle. The loans that the savings banks generate during election years perform worse in the first three years of maturity and loan losses tend to be realized in the middle of the election cycle.

Political lendings of German Savings Banks
A recent paper of the Halle Institute for Economic Research (IWH) suggests that German local politicians take advantage of their influence on the credit decisions of German savings banks. “German savings banks on average increase the supply of commercial loans by €7.6 million in the year of a local election”, says IWH president Reint E. Gropp. Loans that the savings banks generate during election years also perform worse and lead to lower interest income. The results suggest that local politicians take advantage of savings banks to further their chances of re-election.

Global Food Prices and Business Cycle Dynamics in an Emerging Market Economy
Oliver Holtemöller, Sushanta Mallick
Abstract
This paper investigates a perception in the political debates as to what extent poor countries are affected by price movements in the global commodity markets. To test this perception, we use the case of India to establish in a standard SVAR model that global food prices influence aggregate prices and food prices in India. To further analyze these empirical results, we specify a small open economy New-Keynesian model including oil and food prices and estimate it using observed data over the period from 1996Q2 to 2013Q2 by applying Bayesian estimation techniques. The results suggest that big part of the variation in inflation in India is due to cost-push shocks and, mainly during the years 2008 and 2010, also to global food price shocks, after having controlled for exogenous rainfall shocks. We conclude that the inflationary supply shocks (cost-push, oil price, domestic food price and global food price shocks) are important contributors to inflation in India. Since the monetary authority responds to these supply shocks with a higher interest rate which tends to slow growth, this raises concerns about how such output losses can be prevented by reducing exposure to commodity price shocks and thereby achieve higher growth.
