No. 29,

Abstract
In a public good experiment, the paper analyses to which extent individuals with economic education behave differently in a second-order dilemma. Second-order dilemmas may arise, when individuals endogenously build up costly institutions that help to overcome a public good problem (first-order dilemma). The specific institution used in the experiment is a communication platform allowing for group communication before the first-order public good game takes place. The experimental results confirm the finding of the literature that economists tend to free ride more intensively in public good games than non-economists. The difference is the strongest in the end-game phase, yielding in the conclusion that the magnitude of the end-game effect depends on the share of economists in the pool of participants. When it comes to the building-up of institutions, the individual efficiency gain of the institution and its inherent cost function constitute the driving forces for the contribution behaviour. Providing an investment friendly environment yields in economists contributing more to the institution than non-economists. Therefore, we make clear that first-order results of a simple public good game cannot be simply applied for second-order incentive problems.

Banks Credit and Productivity Growth
Fadi Hassan, Filippo di Mauro, Gianmarco Ottaviano
ECB Working Paper,
No. 2008,
2017
Abstract
Financial institutions are key to allocate capital to its most productive uses. In order to examine the relationship between productivity and bank credit in the context of different financial market set-ups, we introduce a model of overlapping generations of entrepreneurs under complete and incomplete credit markets. Then, we exploit firm-level data for France, Germany and Italy to explore the relation between bank credit and productivity following the main derivations of the model. We estimate an extended set of elasticities of bank credit with respect to a series of productivity measures of firms. We focus not only on the elasticity between bank credit and productivity during the same year, but also on the elasticity between credit and future realised productivity. Our estimates show a clear Eurozone core-periphery divide, the elasticities between credit and productivity estimated in France and Germany are consistent with complete markets, whereas in Italy they are consistent with incomplete markets. The implication is that in Italy firms turn to be constrained in their long-term investments and bank credit is allocated less efficiently than in France and Germany. Hence capital misallocation by banks can be a key driver of the long-standing slow productivity growth that characterises Italy and other periphery countries.

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.

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.

German Economy: Strong domestic demand compensates for weak exports
The upturn of the German economy is expected to gain further momentum as a consequence of strong domestic demand. Real gross domestic product is expected to increase by 1.6% in 2016. Consumer prices are expected to rise by 0.9%. Unemployment is expected to rise slightly because it will take time to integrate refugees into the labour market.

Public Bank Guarantees and Allocative Efficiency
Reint E. Gropp, Andre Guettler, Vahid Saadi
Abstract
In the wake of the recent financial crisis, many governments extended public guarantees to banks. We take advantage of a natural experiment, in which long-standing public guarantees were removed for a set of German banks following a lawsuit, to identify the real effects of these guarantees on the allocation of credit (“allocative efficiency”). Using matched bank/firm data, we find that public guarantees reduce allocative efficiency. With guarantees in place, poorly performing firms invest more and maintain higher rates of sales growth. Moreover, firms produce less efficiently in the presence of public guarantees. Consistently, we show that guarantees reduce the likelihood that firms exit the market. These findings suggest that public guarantees hinder restructuring activities and prevent resources to flow to the most productive uses.

Grant Dependence, Regulation and the Effects of Formula-based Grant Systems on German Local Governments: A Data Report for Saxony-Anhalt
Peter Haug
IWH Discussion Papers,
No. 2,
2013
Abstract
Recent empirical studies have found – seemingly − efficiency-enhancing effects of vertical grants on local public service provision. The main purpose of this paper is to prepare an elaborate theoretical and empirical analysis of these contradictory results. Therefore, it investigates if certain fiscal and institutional conditions (fiscal stress, fiscal rank-preserving vertical grant systems, input- and output regulation), that might help to explain these empirical findings, are characteristic of at least some parts of the local government sector or certain regions. The German state of Saxony-Anhalt is chosen for case study purposes. The main results are: First, the local governments suffer from severe fiscal problems such as high grant dependency, low tax revenues and the prevalent inability to finance investments by own resources. Second, the output- and input-regulation density of certain mandatory municipal services (schools, childcare facilities, fire protection) is high. Finally, the most important vertical grant category for local governments, the formula-based grants (“Schlüsselzuweisungen”), can be described as mainly exogenous, unconditional block grants that in most cases preserve the relative fiscal position of the grant recipients.

Efficiency in the UK Commercial Property Market: A Long-run Perspective
Steven Devaney, Oliver Holtemöller, R. Schulz
IWH Discussion Papers,
No. 15,
2012
Abstract
Informationally efficient prices are a necessary requirement for optimal resource allocation in the real estate market. Prices are informationally efficient if they reflect buildings’ benefit to marginal buyers, thereby taking account of all available information on future market development. Prices that do not reflect available information may lead to over- or undersupply if developers react to these inefficient prices. In this study, we examine the efficiency of the UK commercial property market and the interaction between prices, construction costs, and new supply. We collated a unique data set covering the years 1920 onwards, which we employ in our study. First, we assess if real estate prices were in accordance with present values, thereby testing for informational efficiency. By comparing prices and estimated present values, we can measure informational inefficiency. Second, we assess if developers reacted correctly to price signals. Development (or the lack thereof) should be triggered by deviations between present values and cost; if prices do not reflect present values, then they should have no impact on development decisions.

Federal grants for local development to stop economic decline? – Lessons from Germany
Peter Haug, Martin T. W. Rosenfeld
Consequences of the International Crisis for European SMEs – Vulnerability and resilience. Routledge Studies in the European Economy, Routledge,
2012
Abstract
The chapter analyses theoretically and empirically the supply-side effects of the public investments funded by the German „Economic Stimulus Package II“(Konjunkturpaket II), which was implemented in 2009. In the theoretical part, we address the distortionary effects of investment grants on public capital provision and local economic development. According to the theoretical literature on the efficient provision of public goods, public inputs and economic growth, conditional investment grants have several negative allocation effects: First, they distort the relative factor prices for the local government stimulating excess public capital stocks and Pareto-inefficient provision of public goods. Second, long-term growth-enhancing effects of debt-financed public investment could only be expected for public inputs, which either directly increase the productivity of the private sector or increase factor productivity, especially by increasing the stock of human capital. In the empirical part, we find that despite of the recent increase in municipal investments in the German state of Saxony our regression results do not confirm a connection with the ESPII funds. Furthermore, no relationship between the municipal fiscal strength and the amount of ESPII grants received could be found. All in all, due to the focus of the grants on public consumption goods rather than public inputs only marginal future growth effects can be expected from the subsidized investments.

Introducing Financial Frictions and Unemployment into a Small Open Economy Model
Mathias Trabandt, Lawrence J. Christiano, Karl Walentin
Journal of Economic Dynamics & Control,
No. 12,
2011
Abstract
Which are the main frictions and the driving forces of business cycle dynamics in an open economy? To answer this question we extend the standard new Keynesian model in three dimensions: we incorporate financing frictions for capital, employment frictions for labor and extend the model into a small open economy setting. We estimate the model on Swedish data. Our main results are that (i) a financial shock is pivotal for explaining fluctuations in investment and GDP. (ii) The marginal efficiency of investment shock has negligible importance. (iii) The labor supply shock is unimportant in explaining GDP and no high frequency wage markup shock is needed.
