Lang, Günter (2001): Global Warming and German Agriculture: Impact Estimations Using a Restricted Profit Function, Environmental and Resource Economics, 19 (2): 97-112.
Abstract: This study uses the concept of shadow prices for measuring the impacts of climate change. By estimating a restricted profit function rather than a cost or a production function the explanatory power of the model is increased because of an endogenous output structure. Using low aggregated panel data on Western German farmers, the results imply that the agricultural production process is significantly influenced by climate conditions. Simulation results using a 2 CO2 climate scenario show positive impacts for all regions in Germany. Interestingly, the spatial distribution of the gainsis indicating no advantage for those regions, which currently suffer from insufficient temperature. Finally, the importance of an endogenous output structure is confirmed by the finding that the desired product mix will drastically change.

Albers, Sönke (1998): A framework for analysis of sources of profit contribution variance between actual and plan, International Journal of Research in Marketing, 15 (2): 109-122.
Abstract: Marketing controllers traditionally analyze the profit contribution variance between actual and plan by decomposing it into a quantity and a price variance. This, however, enables them only to identify areas where problems exist rather than to diagnose their causes. In order to get more insights, this paper proposes making the planning assumptions for achieving a certain profit contribution explicit beforehand by specifying appropriate response functions. This information can be used after the fact to calculate the amount of profit contribution variance associated with different sources. In particular, the paper offers a novel decomposition principle of total variance into partial variances associated with possible sources such as incorrect market response assumptions (planning variance), deviations of actual marketing actions from planned ones (execution variance) and misanticipation of competitive reactions (reaction variance). Each of these variances can be decomposed further into the separate effects of single marketing instruments. By distinguishing between a response function for market share and one for market size, controllers can also estimate for which part of the variance the product manager may be responsible.

Lang, Günter and Peter Welzel (1998): Technology and Cost Efficiency in Universal Banking A “Thick Frontier”-Analysis of the German Banking Industry, Journal of Productivity Analysis, 10 (1): 63-84.
Abstract: Using 1992 data of 1490 banks covering about 40% of German banking, we specify amulti-product translog cost function and follow the “thick frontier”-approach to control for cost inefficiency when evaluating the technology of banking. Scale economies are found to exist up to a size of about 5 billion DM of total assets, with diseconomies being caused by non-operating costs. There is hardly any evidence of economies of scope. Compared to cost inefficiency external factors play a surprisingly strong role in explaining cost differences between high-cost and low-cost banks. Smaller banks turn out to be more responsive to input prices.

Abstract: This article applies a modern empirical test of conduct to assess competitive conditions in the German banking sector. The elasticity of total revenues with respect to changes in input prices is calculated, using the intermediation approach as model of the banking firm. The functional form of the revenue equation is specified as a Translog function. The empirical basis consists of a panel of 1432 German universal banks with an observation period of at least four years for each of them. To account for potential consequences of the distinct regulatory environment and average bank size, the estimations are run separately for the three subgroups „cooperative banks”, „savings banks” and „credit banks”. The empirical results are consistent with the behavior of monopolistic competition, rejecting significantly the hypotheses of both monopoly and perfect competition. Differences between the subgroups turned out to be small, rejecting a causality from market share on market behavior.
