This paper proposes the evaluation of the New Keynesian Phillips Curve (NKPC) under a new learning mechanism where VAR learning dynamics is combined with the idea of testing the validity of the forward-looking model of inflation dynamics. The key assumption is that agents’ perceived law of...

This study sheds new light on the question of whether or not sentiment surveys, and the expectations derived from them, are relevant to forecasting economic growth and stock returns, and whether they contain information that is orthogonal to macroeconomic and financial data. I examine 16...

This discussion paper led to an article in 'Journal of Economic Theory' (2014). Volume 150, pp. 778-814.<P> We propose behavioral learning equilibria as a plausible explanation of coordination of individual expectations and aggregate phenomena such as excess volatility in stock prices and high...</p>

We provide an analytical approach that facilitates understanding the bifurcation mechanism of a wide class of economic models involving spatial agglomeration of economic activities. The proposed method overcomes the limitations of the Turing (1952) approach that has been used to analyze the...

We develop a methodology for studying ''large deviations type'' questions. Our approach does not require that the large deviations principle holds, and is thus applicable to a larg class of systems. We study a system of queues with exponential servers, which share an arrival stream. Arrivals are...

Macro Models are a series of free Apps available in App Store, and they work with Ipads. Each App simulates a specific macroeconomic model and presents both the static and the dynamic results. The first five Apps developed and published are: the Income-Expenditure model in three versions (I, II...

This article proposes that Okun’s Law is an empirical relationship between employment and production which, in the United States, correlates to the relationship between the radius of a circle and one-half of its circumference i.e. numerically, the ratio 1 : .. This requires two new sets of...

This study examines the expectational stability of the rational expectations equilibria (REE) under alternative Taylor rules when trend inflation is non-zero. We find that when trend inflation is high, the REE is likely to be expectationally unstable. This result holds true regardless of the...

This study examines the expectational stability of the rational expectation equilibria(REE) under Taylor rules when trend inflation is non-zero. We find that whether or not a higher (lower) trend inflation makes the REE more (less) unstable depends largely on the data (such as contemporaneous...
