Dr Katsuyuki Shibayama

Lecturer in Economics

School of Economics, Keynes College, B1.02

Katsuyuki Shibayama is Library Liaison Officer and Equality, Diversity and Inclusivity Officer


After completing his BA in Economics at Waseda University (Tokyo) in 1993, Katsuyuki spent seven years as a market economist in Nomura Research Institute (Economic Research Division), Nomura Securities (Fixed Income School) and Deutsche Bank Tokyo (Global Markets Research). His main duty was analysing and forecasting Japanese economic conditions and monetary policy to support the traders and sales persons of Japanese government bonds. In 2000 he restarted his economics study at the London School of Economics and was awarded his PhD in Economics in 2007. 

Katsuyuki currently teaches financial economics for BSc and MSc students. His research interest is in the area of macro and monetary economics. In particular, he studies the role of inventories in business cycles and general properties of dynamic stochastic general equilibrium models.

Katsuyuki is a member of MaGHiC (Macroeconomics, Growth and History Centre) and KCF (Kent Centre for Finance).

Inventories in business cycles

My objective is to investigate the role of inventories in business cycles by means of the methods that meet academic standards. I am especially interested in so-called inventory cycles (see Figures). Inventory cycles have the cycle length close to the post-war average of the length of one business cycle in Japan and the US (3-5 years) and it seems to me that the cycles are fairly stable over time. While inventory cycles are well known among practitioners such as market economists, the cycles are only rarely studied by academic researchers.


General Properties of Dynamic Stochastic General Equilibrium Models

Most theoretical researches in economics are built upon specific 'models'. On the contrary, my aim is to reveal the properties of a general class of models. For example, in a broad class of models, the local behaviours of individual economic agents near the equilibrium is governed by the second order optimality conditions (ie the Jacobian of FOCs must be a negative definite Hessian). My specific research topics in this area include numerical solution methods for imperfect information models and equilibrium selection in sunspot equilibria.

PhD supervision

Katsuyuki is interested in supervising PhD students in dynamic stochastic general equilibrium models in general (in terms of methodology). He however expects students to have their own interesting motivations or questions to be addressed within that framework.
