The book introduces the New Keynesian framework, historically through a literature overview and through a step-by-step derivation of a New Keynesian Phillips curve, an intertemporal IS curve, and a targeting rule for the central bank. This basic version is then expanded by introducing cost and demand shocks and uncertainty. The latter enters the model via second order Taylor approximation instead of linearization. Bringing all equations together results in an equilibrium condition which is simulated with a wide range of parameter values, including possible crisis scenarios. The author finds that accounting for uncertainty – regarding growth and inflation expectations – can lead to lower nominal interest rates set by the central bank. Contents · Historical recapitulation of DSGE Modeling · Derivation of a basic New Keynesian Model · Augmentation with persistent shocks and uncertainty · Comparative statics and a wide range of numerical simulations · Mathematical concepts and background information in the appendix Target Groups · Researchers and graduate students in macroeconomics and monetary policy · Managers and practitioners in the fields of monetary economics The Author Tobias Kranz obtained his Master of Science degree in Economics at the University of Trier in 2015. He has been working as postgraduate at the chair of Empirical Economics (University of Trier) since 2016. .

This is the first monograph that discusses in detail the interactions between Fourier analysis and dynamic economic theories, in particular, business cycles. Many economic theories have analyzed cyclical behaviors of economic variables. In this book, the focus is on a couple of trials: (1) the Kaldor theory and (2) the Slutsky effect. The Kaldor theory tries to explain business fluctuations in terms of nonlinear, 2nd-order ordinary differential equations (ODEs). In order to explain periodic behaviors of a solution, the Hopf-bifurcation theorem frequently plays a key role. Slutsky's idea is to look at the periodic movement as an overlapping effect of random shocks. The Slutsky process is a weakly stationary process, the periodic (or almost periodic) behavior of which can be analyzed by the Bochner theorem. The goal of this book is to give a comprehensive and rigorous justification of these ideas. Therefore, the aim is first to give a complete theory that supports the Hopf theorem and to prove the existence of periodic solutions of ODEs; and second to explain the mathematical structure of the Bochner theorem and its relation to periodic (or almost periodic) behaviors of weakly stationary processes. Although these two targets are the principal ones, a large number of results from Fourier analysis must be prepared in order to reach these goals. The basic concepts and results from classical as well as generalized Fourier analysis are provided in a systematic way. Prospective readers are assumed to have sufficient knowledge of real, complex analysis. However, necessary economic concepts are explained in the text, making this book accessible even to readers without a background in economics.

This book addresses collective bargaining in an intertemporal monetary macroeconomy of the aggregate supply–aggregate demand (AS–AD) type with overlapping generations of consumers and with a public sector. The results are presented in a unified framework with a commodity market that clears competitively. By analyzing the implications of three variants of collective bargaining – efficient bargaining in a uniform and a segmented labor market and “right-to-manage” wage bargaining – it identifies the quantity of money, price expectations, union power, and union size as the determinants of temporary equilibria. In the three scenarios, it characterizes and compares the temporary equilibria using both analytical and numerical techniques, with an emphasis on allocations, welfare, and efficiency. It also discusses the dynamic evolution under rational expectations and its steady states in nominal and real terms. Lastly, it demonstrates conditions for stability regarding a balanced monetary expansion of the economy.

This report is a partial result of the China’s Quarterly Macroeconometric Model (CQMM), a project developed and maintained by the Center for Macroeconomic Research (CMR) at Xiamen University. The CMR is one of the Key Research Institutes of Humanities and Social Sciences sponsored by the Ministry of Education of China, focusing on Chinese economic growth and macroeconomic policies. The CMR started to develop the CQMM for purpose of short-term forecast, policy analysis, and simulation in 2005. Based on the CQMM, the CMR with its partners hold press conferences to release forecasts for China’ major macroeconomic variables. Since July 2006, twenty-seven quarterly reports titled Chinese Macroeconomic Outlook have been presented and thirteen annual reports have been published. .

This book presents both methodological papers on and examples of applying behavioral predictive models to specific economic problems, with a focus on how to take into account people's behavior when making economic predictions. This is an important issue, since traditional economic models assumed that people make wise economic decisions based on a detailed rational analysis of all the relevant aspects. However, in reality – as Nobel Prize-winning research has shown – people have a limited ability to process information and, as a result, their decisions are not always optimal. Discussing the need for prediction-oriented statistical techniques, since many statistical methods currently used in economics focus more on model fitting and do not always lead to good predictions, the book is a valuable resource for researchers and students interested in the latest results and challenges and for practitioners wanting to learn how to use state-of-the-art techniques. .

This highly original book develops a systematic zero-net-profit comparative statics theory of the firm that challenges many widely held views in microeconomics. It builds a bridge between the marginalist long-run theory of the firm and Sraffian theory to create a unified theoretical framework that explains how firms react to exogenous shocks resulting in new equilibrium positions of the whole economy. The central message of the book is that too often economists expect more from the microeconomic laws of input demand and output supply than they can really give. The authors show that the zero-net-profit condition requires a more articulated analysis that sometimes yields qualitative results contrary to those of familiar economic laws. Written for academic researchers and graduate students, the book will be of particular interest to those working on the microeconomics of industry equilibrium, comparative statics and Sraffian economics.
