Abstract
At the latest since the oil crisis in the beginning of the 1970s, energy efficiency of homes became a widely discussed topic. In the past, it were in first line aspects of the scarcity of fossil energy sources that motivated the debate. Nowadays, climate protection is a main goal of the European energy policy. For this purpose, a new instrument was introduced in 2009. Europe-wide, the “Energy Performance Certificate” for buildings presents detailed information on the required energy for heating, warm water and (indirectly) the resulting costs for tenants. This instrument is designed to provide further information for consumers to influence their behavior in favor of energy efficient buildings.
Until now, there is only little information on spatial aspects of the energy efficiency of housing in Germany. This article presents data on the level of Germany’s NUTS2 regions. In our calculations, we include information on more than 2.6 million flats, interpolating it representatively for the total stock of multifamily buildings and considering the regional climate.
The results of the first ista-IWH-Energy-Efficiency-Index indicate large differences between regions. The required energy for housing is much lower in the eastern and southern parts of Germany, compared to the western or northern parts. Explanations can be seen in a different structure of the housing stock (e.g. age of construction, level of refurbishment). Moreover, first analyses of the market structure indicate that owner occupied flats are more efficient in energy requirement than rental flats. Vacancy rates, the duration of occupation of rented flats and the level of regional income play an additional role for the energy efficiency of the regional housing stock.

Public Housing and the Fear of Private Equity – Assessing Social Impacts
Dominik Weiß
Wirtschaft im Wandel,
No. 12,
2008
Abstract
This contribution examines the consequences of sales of municipal flats to private investors, which have been criticised strongly for social reasons. An evaluation of the German Socio-Economic Panel Study (SOEP) from 1999 to 2006 reveals no serious consequences of the privatisation of municipal flats on the affected households. It cannot produce empirical evidence to foster arguments for the public criticism of the public housing sales. The essential results from this sample point to moderate rent increases and above-average investment activity after the privatisation. However, the analysis of the household´s sentiment whether the total expense load for the flat is adequate shows that tenants in privatised flats found their flat increasingly expensive. A possible reason for this development might be the lower mobility of the residents of municipal flats.

Rents and Quality of Life in Eastern Germany
Dominik Weiß
IWH Discussion Papers,
No. 12,
2008
Abstract
The rent levels between East- and Westgermany differ less than one Euro on average. This difference seems very slow regarding the persistant economic disparities and high vacancy rates in East-Germany.
Based on the assumtion, that income and life quality aspects have an impact on the local rent level a set of variables is regressed on the rent of several housing quality segments in a cross-section analysis at the community-level. The regression contains demographic, economic and housing-market-related variables and a dummy variable for east germany. It incorporates hypotheses about a special supplier structure and several market interventions that are related to the transformation process from socialistic into market economic structures after the reunification in the 1990s.
The results show a significant positive coeficiant for the east german dummy in two segments of the housing stock. Further Research about the reasons for the extra charge are important, because theese findings may be responsible for the continous out migration from East Germany.

Africa – Commodity Dependence, Resource Curse and Export Diversification. African Development Perspectives Yearbook 2007, Vol. 12

Abstract
This Volume 12 of the African Development Perspectives Yearbook deals - in the form of country cases and country units - with African countries' state of commodity dependence, their efforts for export diversification, and their vulnerability to crises and disasters. These problems are considered in the context of the continent's abundance of natural resources, especially the strategic oil resources. African countries' high dependency on a few primary export goods is one of the reasons for their vulnerability to conflicts. In this volume of the African Development Perspectives Yearbook, the focus is on the vulnerability of resource-rich, mainly oil-exporting, African countries. Strategies of export diversification, options how to overcome political instabilities that impede investment, and strategies how to work towards reconstruction and sustainable economic and political development are discussed by highlighting examples from various resource-rich countries. It is analysed how these countries can manage to escape from the primary commodities dilemma by pro-active economic policies and especially by solving political conflicts that have arisen from resource rent.

The East German Cement Cartel: Cartel Efficiency and Policy after Economic Transformation
Ulrich Blum
Eastern Economic Review,
2007
Abstract
In 2003 the German Antitrust Commission (GAC) proved the existence of a cartel in the German cement industry. The German cement producers involved in the case were fined € 661 million for having established quotas to extract additional rents. One of the main centers of this cartel was East Germany, where the East German Cement Combine with its giant facilities had been sold, in the early 1990s, to four large producers by Treuhand in the process of privatizing the economy. Only in respect to in this market did all defendants concede having had a part in forming a cartel.
In this paper, we challenge the argument of excess revenue that the GAC puts forward for the East German market. We argue that legal evidence does not necessarily translate into economic evidence. We show that demand for cement is realized in geographical and, to a more limited extent, in product space. Thus, in the absence of cartels we would expect monopolistic competition to prevail. We argue that any transition in the market regime, from the cartel to the post cartel period, must be traceable in the individual firm’s demand function which differs from the clients’ demand function because of costs for spatial and product differentiation. Within the framework of an econometric model, we cannot identify any structural changes in demand. Most likely, imports from Poland and the Czech Republic were dumped into the East German market and some medium sized producers were responsible for the cartel never working.
Finally the paper shows how difficult it is to generate competition in certain industries even under the umbrella of a well-established market economy, i.e. that of West Germany, and that the openness of the economy, i.e. trans-border shipments, are decisive.

Do House Prices Drive Aggregate Consumption?
Marian Berneburg, Axel Lindner
Wirtschaft im Wandel,
No. 10,
2006
Abstract
In recent times increasing house prices have been credited with a stong positive influence on aggre-gate consumption. But it is questionable in how far higher prices are at all able to lift the purchasing power of the economy as whole: The seller’s profit of a high price, equals the buyer’s loss. But while a positive correlation between house prices and consumption is evident, it is not a sign of irra-tional behaviour by market participants. In fact it seems that both factors are driven by other pa-rameters: the interest rate and expectations about future interest rates and economic activity. For a selection of four developed countries, the follow-ing article tries to give an explanation for the house price developments of the past 15 years. While disregarding country specific risk as well as institutional aspects and demographic factors, a present value caluclation forms the basis for esti-mating a fundamentally justified price movement. Expectations for future rents and discount rates are being proxied by a moving average of past values. It can be observed how interest rate changes and long-run economic growth, two as-pects that clearly also drive private consumption, play a key role here.

Pension with 67? – A comment
Herbert S. Buscher
Wirtschaft im Wandel,
No. 2,
2006
Abstract
In der Antike, so wird es überliefert, wurde der Überbringer schlechter Nachrichten nach der Übermittlung getötet. War die Nachricht, das Renteneintrittsalter von derzeit 65 Jahren schrittweise auf 67 Jahre zu erhöhen, eine schlechte Nachricht? Die Antwort ist eindeutig nein. Denn die Verlängerung der Lebensarbeitszeit bzw. die Erhöhung des Eintrittsalters ist eine richtige und notwendige Entscheidung, will doch die Mehrzahl der Arbeitnehmer auch zukünftig, wenn sie in den Ruhestand wechseln, eine Rente beziehen. Es ist seit Jahren bekannt, daß die gegenwärtigen sozialen Sicherungssysteme in ihrer derzeitigen Form nicht mehr haltbar sind und deswegen dringend reformiert werden müssen. Ebenfalls liegen seit Jahren die entsprechenden Vorschläge hierfür auf den Tisch – allerdings hatte die Politik lange Zeit nicht den Mut, frühzeitig mit den notwendigen Reformen zu beginnen. Statt dessen hat sie es in der Vergangenheit unterlassen, die Bevölkerung systematisch auf die erforderlichen Veränderungen einzustimmen. Eher das Gegenteil ist der Fall. Mit den vielfältigen Programmen zur Frühverrentung wollte die Politik den Arbeitsmarkt entlasten und die Arbeitslosigkeit „senken“. Hierdurch suggerierte sie der Öffentlichkeit, daß ein früheres Rentneralter nicht nur möglich, sondern auch finanzierbar sei und den Rentenbeziehern eine „ausreichende“ Rente gezahlt werden könne.

Globalisierung als Chance
Ulrich Blum
Globalisierung - Chance oder Risiko für Osteuropa,
2005
Abstract
Die Chancen der Globalisierung werden durch Tatbestände des Markt- und des Wettbewerbsversagens beschränkt. Diese sind aus verschiedenen Gründen teilweise nicht zu umgehen, teilweise aber auch zu vermeiden. Maßgeblich hierfür sind die Transaktionskosten; dabei gilt das ökonomische Kalkül, daß die aufzubringenden Kosten einer entsprechenden Änderung nicht höher sein dürfen als die diskontierten Rückschlüsse der Nutzen. Oft werden aber auch Versagenstatbestände deshalb aufrechterhalten, weil dies Folge des Auseinanderklaffens von individueller und kollektiver Rationalität ist: Aus kollektiven Gründen müßte ein Wechsel des Arrangements erfolgen, dies ist aber individuell nicht durchsetzbar, beispielsweise infolge der Aktivitäten von pressure groups oder aufgrund der Interessenslage der Politik. In der globalen Welt werden Standortunterschiede eingeebnet und die Möglichkeit des Staates zur Besteuerung reduziert sich auf die Rente, die ein Unternehmen an einem gegebenen Standort erzielen kann. Damit wird die beste Standortpolitik eine solche, die versucht, derartige Renten zu maximieren, indem sie vor Ort hochattraktive Potentialfaktoren institutionalisiert.

Sind Haushalte mit Wohneigentum sparsamer als Mieterhaushalte?
Ruth Grunert
IWH Discussion Papers,
No. 171,
2003
Abstract
In this paper examines the data of the income and consumption survey of 1998 with regard to savings and wealth. Households owning their property (owner households) and households renting the property (tenant households) are analysed seperatly and then compared. For further insight these two groups are also devided into East and West German households. In 1998, almost half of the West German and almost a quarter of the East German private households owned property they occupied themselves. The average owner household saves a monthly amount three times as large as the tenant household. The decisive economizing motive for the owner households is servicing its mortgages and loans. However, at the same time, there is the necessity to form reserves for the property maintainance as well as the renovation. In comparison to tenant households, owner households which no longer have to service mortgages or loans, have a higher average rate of saving. The estimate of the saving by means of regression analysis confirms the significant positive influence of the “owner” status on savings. However, in every estimate the houshold’s income proves to be the main influence on savings activity.

Relationship Lending within a Bank-Based System: Evidence from European Small Business Data
Hans Degryse, Patrick Van Cayseele
Journal of Financial Intermediation,
No. 1,
2000
Abstract
We investigate relationship lending using detailed contract information from nearly 18,000 bank loans to small Belgian firms operating within the continental European bank-based system. Specifically, we investigate the impact of different measures of relationship strength on price and nonprice terms of the loan contract. We test for the possibility of rent shifting by banks. The evidence shows two opposing effects. On the one hand, the loan rate increases with the duration of a bank–firm relationship. On the other hand, the scope of a relationship, defined as the purchase of other information-sensitive products from a bank, decreases the loan's interest rate substantially. Relationship duration and scope thus have opposite effects on loan rates, with the latter being more important. We also find that the collateral requirement is decreasing in the duration of the relationship and increasing in its scope.
