The state as a pioneering customer: How public demand can drive private innovation
Especially in technology-intensive industries, demand from the state can expand private markets and create incentives for privately funded research and development, a new study by the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association shows.

Worse ratings by U.S. rating agencies for European sovereigns no argument for European rating agency
A new study by the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association shows that the major U.S. rating agencies rated European sovereigns significantly worse than Fitch, which is more “Europe oriented”. Although the findings in part support the claim of some European politicians during the recent debt crisis that there was an “anti-Europe” bias of the U.S. agencies, the study shows that a new European agency would not address this problem. The reason: Market participants would not listen to the new agency.

New look and feel for IWH website
The relaunched website of the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association goes live today. After the successful launch of a new corporate design at the beginning of the year, IWH now presents itself also digitally in a new and adjusted way. The redesigned website focuses on IWH’s core issues and provides information tailored to each target group. Due to the responsive design, the new website can be perfectly read and navigated on smartphones and tablets as well.

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 Perception of Financial Inferiority Nurtures Negative Attitudes Towards Foreigners
When people feel that their own economic status is inferior to the economic status of a relevant peer group, it becomes more likely that they develop negative attitudes towards foreigners. This link was found in a new study of the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association. The effect is particularly strong with respect to foreigners from low-wage countries.

Effects of Incorrect Specification on the Finite Sample Properties of Full and Limited Information Estimators in DSGE Models
Sebastian Giesen, Rolf Scheufele
Journal of Macroeconomics,
June
2016
Abstract
In this paper we analyze the small sample properties of full information and limited information estimators in a potentially misspecified DSGE model. Therefore, we conduct a simulation study based on a standard New Keynesian model including price and wage rigidities. We then study the effects of omitted variable problems on the structural parameter estimates of the model. We find that FIML performs superior when the model is correctly specified. In cases where some of the model characteristics are omitted, the performance of FIML is highly unreliable, whereas GMM estimates remain approximately unbiased and significance tests are mostly reliable.

Much Ado About Nothing: Sovereign Ratings and Government Bond Yields in the OECD
Makram El-Shagi
IWH Discussion Papers,
No. 22,
2016
Abstract
In this paper, we propose a new method to assess the impact of sovereign ratings on sovereign bond yields. We estimate the impulse response of the interest rate, following a change in the rating. Since ratings are ordinal and moreover extremely persistent, it proves difficult to estimate those impulse response functions using a VAR modeling ratings, yields and other macroeconomic indicators. However, given the highly stochastic nature of the precise timing of ratings, we can treat most rating adjustments as shocks. We thus no longer rely on a VAR for shock identification, making the estimation of the corresponding IRFs well suited for so called local projections – that is estimating impulse response functions through a series of separate direct forecasts over different horizons. Yet, the rare occurrence of ratings makes impulse response functions estimated through that procedure highly sensitive to individual observations, resulting in implausibly volatile impulse responses. We propose an augmentation to restrict jointly estimated local projections in a way that produces economically plausible impulse response functions.

Buy, Keep, or Sell: Economic Growth and the Market for Ideas
Ufuk Akcigit, Murat Alp Celik, Jeremy Greenwood
Econometrica,
No. 3,
2016
Abstract
An endogenous growth model is developed where each period firms invest in researching and developing new ideas. An idea increases a firm's productivity. By how much depends on the technological propinquity between an idea and the firm's line of business. Ideas can be bought and sold on a market for patents. A firm can sell an idea that is not relevant to its business or buy one if it fails to innovate. The developed model is matched up with stylized facts about the market for patents in the United States. The analysis gauges how efficiency in the patent market affects growth.
