    Business cycles and institutions : empirical analysis
    (2017) Kufenko, Vadim; Hagemann, Harald
    The cumulative dissertation covers diverse aspects of empirical analysis of business cycles and institutions. There are three research questions in focus. To address the interplay between business cycles and institutions, the first research question is formulated: could the Malthusian cycles be present in a frontier economy with abundance of land and which institutions could be responsible for the Malthusian regime and the transition from it? In order to consider the far-reaching implications of economic cycles for the development of economic thought, the second question is stated: can economic fluctuations quantitatively influence research output? To address the methodology of business cycle analysis, the third question is brought up: how may spurious periodicities emerge and how could one test for them? The main findings in the cumulative dissertation can be summarized as follows: i) it is shown that institutional arrangements may form economic constraints or build-up on the existing ones, responsible for the regimes in which cyclical fluctuations take place; ii) the interaction between the economic cycles and fluctuations in bibliometric variables representing research output in Economics as a science is analysed, and empirical evidence suggests the downswings of cycles stimulate more publications on the topic of crises and business cycles; iii) spurious periodicities emerge close to filtering bounds for real and simulated data after detrending, and it is demonstrated that simultaneous significance testing of spectral density peaks against the noise spectrum across different types of signals may help to reveal spurious periodicities.

    Business cycles in the economy and in economics : an econometric analysis
    (2015) Geiger, Niels; Kufenko, Vadim
    It is sometimes pointed out that economic research is prone to move in cycles and react to particular events such as crises and recessions. The present paper analyses this issue through a quantitative analysis by answering two closely related research questions: (1) whether or not there are patterns in the economic literature on business cycles, and (2) whether or not these are correlated with movements in actual economic activity. To tackle these questions, a bibliometric analysis of key terms related to business cycle and crises theory is performed. In a second step, these results are confronted with data on actual economic developments in order to investigate the question of whether or not the theoretical literature follows trends and developments in economic data. Respective time series are detrended by the Kalman filter in order to estimate cycles. To determine the connection between economic activity and developments in the academic literature, a descriptive analysis is scrutinized by Granger causality tests. The paper also includes IRF analysis for quantitative assessment of the effects from economic to bibliometric variables. The results point towards a confirmation of the hypothesis of an effect of business cycles and crises in economic variables on discussions in the literature.
