Business economics in a post-truth era

Business economists face increasing challenges at this political and policymaking juncture. “Experts” and economists are out of favor with the public and with certain policymakers. In response, business economists should be frank about our failures and the limits of our models. We can then be ready to defend truth against falsehood. In our defense of fact-based decision making, we must first assert that data matter, and the unbiased integrity of that data matters. We must support and defend the work of the Bureau of Economic Analysis, the Bureau of Labor Statistics, and the Census Bureau. Business economists must be story tellers, transmitting historical memory of past crises, of past attacks on our profession and data sources (such President Nixon’s targeting of the Bureau of Labor Statistics).     

What is the potential growth rate of the U.S. economy,and how might policy affect it?

The answer to the question “What will future potential growth be?” is as important as it is unknowable. This paper attempts to predict future U.S. potential output growth by combining what is unknown (future productivity growth, the performance of the labor market) with what is known (the evolution of the age structure of the population). It does so in two ways. First, this paper uses the historical experience of potential labor productivity growth, labor force participation, and weekly hours to simulate a range of outcomes for future potential growth—finding a 90% confidence interval that ranges from 0.7% annual growth to 3.0% annual growth, centered by construction around the Congressional Budget Office projection of 1.8% annual growth. Second, the paper examines a range of specific economic policies that the Trump Administration might pursue in terms of their impact on economic growth both in the short run and over the next decade—finding that an outer bound of these policies could be plus or minus 0.5 percentage point on the annual growth rate, but that these policies would most likely subtract a small amount from growth.     

Steuerpolitik und Wirtschaftswachstum

The design of the tax system matters for economic growth. During times of economic crisis, tax instruments such as temporary tax cuts can be used to soften adverse effects on the economy by stimulating private and corporate spending. However, empirical evidence suggests that the overall impact of short term tax policies is limited. In the long run, the structure of the tax system is essential to building up an investment friendly and innovation-stimulating environment, which will promote sustainable economic growth.     

Rundfunkfinanzierung: von Gebühren und Beiträgen jetzt zur Indexierung?

The 2013 reform of the system for federal funding for public broadcasting has not put the issue to rest, as the reform has been followed by many critical voices. For example, the public broadcaster ARD now suggests linking its funding to GDP. As different types of funding streams alter how efficient and effectively public broadcasters can pursue their non profit goals, this article analyses options for funding public broadcasting. It seems that a mixed approach would serve as a possible solution.     

Niedrigzinsen bei Bausparkassen — ein Urteil des Bundesgerichtshofs

At the end of February 2017 the Federal High Court of Justice rules that building societies are allowed to terminate old contracts ahead of schedule. A lot of old contracts are problematic in the viewpoint of building societies due to high deposit interest rates. High deposit interest rates are dangerous for building societies in times of low interest rates, especially if low interest rates are long-lasting. The Federal High Court of Justice follows the opinion of the building societies that during saving periods, building societies can be seen as borrowers, and borrowers have the (exceptional) right to terminate contracts after ten years, which is established in the German Civil Law. A microeconomic intertemporal consumption model calculates this as an overreaction byf the Court: Building societies should only be allowed to reduce deposit interest rate to be compensated for non existing loan contracts.     

False Discoveries und Fehlinterpretationen wissenschaftlicher Ergebnisse

High-quality science communication to the public depends to a large extent on the way research findings are translated into comprehensible language and common speech. In this communicative process, a reasonable evaluation of the trustworthiness of empirical findings, based on an adequate interpretation of statistical analyses, is absolutely crucial. This paper’s authors argue that the credibility of science is jeopardised by two compromising developments within science itself: on the one hand, an inflation of ostensible empirical evidence related to misuses and misinterpretations of the concept of statistical significance, and, on the other, a sensationalist overvaluation of the results of single studies instead of an adequate representation of the available body of evidence in a given scientific field.     

Übernivellierung der Einnahmen aus der Grunderwerbsteuer im künftigen Finanzausgleich

Fiscal Equalisation in Germany provides substantial fiscal redistribution between federal and state and among state governments. However, there is also a degree of tax autonomy for the individual German states. Since 2007, states can adjust their local rate of the Real Estate Transfer Tax. However, if they keep the rate low, they may suffer revenue losses due to fiscal redistribution. The paper considers whether this effect will also be present in the new rules for fiscal equalization which will come in to effect in 2020.
