Der deutsche Bankensektor

Although Germany’s banking sector has experienced a wave of consolidation, especially since the financial crisis, the country is still home to a high number of banking institutions. When domestic economic activity was sluggish in the mid-2000s, German banks searched for sources of income abroad; some of them have massively invested in structured products. As a consequence, the financial crisis of 2007–2009 has hit German banks harder than those from other eurozone countries. The European Commission has played a key role in restructuring the sector, asking in particular that banks which have received state aid strongly reduce their balance sheets — and ordering the liquidation of one of them. Since 2010 the German banking sector has returned to the profit zone and appears more robust thanks to an increase of equity and a reduction of balance sheets. The leverage ratio remains nevertheless significant, profitability remains low in a context of strong competition on the domestic market, and some banks find themselves deeply affected by the crisis of the shipping sector.     

Reviewing South Africa's marketing and trade policies for genetically modified products

South Africa is unique in that it has commercialised genetically modified (GM) crops and has a functional biosafety system, which allows for trade in both GM and non-GM crops, despite being surrounded by countries banning the use of GM products. This paper analyses the past achievements and evolving changes in marketing and trade policies for GM products in South Africa. A quantitative analysis of South Africa's GM imports and exports demonstrates the success of South Africa's flexible regulatory system. Yet a review of recent reforms indicates a trend towards more rigid trade and marketing regulations of GM products. This paper suggests five policy recommendations to improve rather than rigidify regulations and allow South Africa to adapt to global changes, manage risks and take advantage of potentially promising new GM technologies.     

Calculating load factors for the transatlantic airline market using supply and demand data – A note on the identification of gaps in the available airline statistics

This paper takes a critical view of the verification of load factors for the direct transatlantic airline market by combining supply and demand-data. The supply-related data originate from the Official Airline Guide, a well-known data source that contains information on scheduled flights. The demand-related data originate from the Marketing Information Data Transfer database, a data set containing information on actual airline bookings. Combining both data sets enables us to calculate the seat occupancy of direct flights between North-West Europe and the US for 2001. Based on the results, we assess the utility of the joint use of these data sources for aviation economic research, and identify various gaps in the available airline statistics.     

Assessing the Implementation Effects of the Biosafety Protocol's Proposed Stringent Information Requirements for Genetically Modified Commodities in Countries of the Asia Pacific Economic Cooperation

We analyze the potential effects of a generalized implementation of the Cartagena Protocol on Biosafety's proposed stringent information requirements on countries, members of the Asia Pacific Economic Cooperation (APEC). This rule would request all traded shipments containing living modified organisms intended for food, feed, or processing to carry a label with the list of precise genetically modified (GM) events in the shipments. We find that the benefits of such requirements are largely debatable and that this regulation would add significant implementation costs for importers of GM crops, for Protocol members adopting new GM crops, and for countries ratifying the Protocol.     

How can our cars become less polluting? An assessment of the environmental improvement potential of cars

This paper presents a systematic overview of the environmental impacts of new average diesel and petrol cars from a life cycle perspective. An analysis of different technical and non-technical improvement options that could be achieved at each stage of a car’s life cycle was performed. The consequences of the adoption of these options on the environment were estimated. The results show that some of the options analysed could have a major positive impact on the vehicle efficiency and induce large improvements of the environmental profile of passenger cars. The highest improvements are achievable through more efficient power trains (including hybrid car), and through lightweight cars. For some options, burden shifts from one car life cycle phase to another, or from one environmental problem to another, can occur. The results show that besides the purely technological options, those that imply behavioural changes by the driver may also reduce the environmental burden substantially.     

The life cycle of authenticity: neo-nomadic tourism culture in Kazakhstan

The paper presents the findings related to the stages of life cycle of authenticity where Kazakhstani nomadic culture in a post-Soviet heritage evolves towards tourist consumption. Using a qualitative case-study research approach, the analysis of data traces stakeholders’ perception of authenticity of various elements of Kazakhstani cultural tourism. The study intertwines inextricably with the processes of authenticity, commodification and cultural change as Kazakhstani traditions have evolved to a neo-nomadic tourism culture where authenticity becomes a currency at play and a point of differentiation from other tourism destinations. The findings offer an original approach to understand the transformation of authenticity at various stages of Kazakhstani tourism development and explore how authenticity is positioned in the influx of tourists and supporting roles from local governments and organisations.     

Gamson's Law versus non-cooperative bargaining theory

We compare Gamson's Law, a popular empirical model of legislative bargaining, with two non-cooperative bargaining models in three players divide the dollar games in which no player has enough votes to form a winning coalition on their own. Both of the game theoretic models better organize the comparative static data resulting from changes in nominal bargaining power than does Gamson's Law. We also identify deviations from the point predictions of the non-cooperative bargaining models. Namely, proposer power is not nearly as strong as predicted under the Baron–Ferejohn model, and a significant number of bargaining rounds tend to take more than two steps under demand bargaining and more than one stage under Baron–Ferejohn, counter to the models' predictions. Regressions using the experimental data provide results similar to the field data, but fail to do so once one accounts for predictions regarding coalition composition under Gamson's Law.     

General equilibrium with nonconvexities and money

In a general-equilibrium economy with nonconvexities, there are sunspot equilibria with good welfare properties; sunspots can ameliorate the effects of the nonconvexities. For these economies, we show that agents act as if they have quasi-linear utility functions. We use this result to construct a new model of monetary exchange along the lines of Lagos and Wright, where trade occurs in both centralized and decentralized markets, but instead of quasi-linear preferences we assume general preferences but with indivisible labor. This suggests that modern monetary theory is more robust than one might have thought. It also constitutes progress on the classic problem of integrating monetary economics and general-equilibrium theory.     

Infinitely repeated games in the laboratory: four perspectives on discounting and random termination

This paper compares behavior under four different implementations of infinitely repeated games in the laboratory: the standard random termination method [proposed by Roth and Murnighan (J Math Psychol 17:189–198, 1978)] and three other methods that de-couple the expected number of rounds and the discount factor. Two of these methods involve a fixed number of repetitions with payoff discounting, followed by random termination [proposed by Sabater-Grande and Georgantzis (J Econ Behav Organ 48:37–50, 2002)] or followed by a coordination game [proposed in (Andersson and Wengström in J Econ Behav Organ 81:207–219, 2012; Cooper and Kuhn in Am Econ J Microecon 6:247–278, 2014a)]. We also propose a new method—block random termination—in which subjects receive feedback about termination in blocks of rounds. We find that behavior is consistent with the presence of dynamic incentives only with methods using random termination, with the standard method generating the highest level of cooperation. Subject behavior in the other two methods display two features: a higher level of stability in cooperation rates and less dependence on past experience. Estimates of the strategies used by subjects reveal that across implementations, even when the discount rate is the same, if interactions are expected to be longer defection increases and the use of the Grim strategy decreases.     

DIRECT MULTI-STEP ESTIMATION AND FORECASTING

Abstract.  This paper surveys the literature on multi-step forecasting when the model or the estimation method focuses directly on the link between the forecast origin and the horizon of interest. Among diverse contributions, we show how the current consensual concepts have emerged. We present an exhaustive overview of the existing results, including a conclusive review of the circumstances favourable to direct multi-step forecasting, namely different forms of non-stationarity and appropriate model design. We also provide a unifying framework which allows us to analyse the sources of forecast errors and hence of accuracy improvements from direct over iterated multi-step forecasting.
