In this paper the relationships between crude oil and refined product prices are investigated in a multivariate framework. This allows us to test several (partly competing) assumptions of earlier studies. In particular, we find that the crude oil price is weakly exogenous and that the spread is constant in some but not all relationships. Moreover, the multivariate analysis shows that the link b...

Financial innovation has increased diversification opportunities and lowered investment costs, but has not reduced the relative cost of active (informed) investment strategies relative to passive (less informed) strategies. What are the consequences? I study an economy with linear production technologies, some more risky than others. Investors can use low quality public information or collect h...

This paper characterizes Federal Reserve policy since 1980 as one that actively manages short-term nominal interest rates in order to control inflation and evaluates this policy using a dynamic, stochastic, sticky-price model of the United States economy. The results show that the Fed’s policy insulates aggregate output from the effects of exogenous demand-side disturbances and, by calling for ...

We present a simple menu cost model which explains the finding that firms are more likely to adjust prices upward than downward. Asymmetric adjustment to shocks arises naturally, even without trend inflation, from the desire of firms to keep industry prices as high as is sustainable and the non-convexity due to menu costs. It implies that aggregate demand shocks have asymmetric effects — negati...

This paper provides new evidence that estimates obtained from aggregated data may not provide reliable estimates of average firm-level parameters, if the composition of producers with different levels of productivity changes over the business cycle. I examine plant-level data and show that, due to the countercyclical reallocation of output among heterogenous plants, productivity measures based ...

Structuralist and post Keynesian models differ in their assumptions about firms’ investment behavior and pricing/output decisions. This paper compares three benchmark models: Kaleckian, Robinsonian and Kaldorian. We analyze the implications of these models for the steady growth path and the cyclical properties of the economy, and evaluate the consistency of the theoretical predictions with empi...

Engel and Wang (2008) argue that trade in durable goods is important for international real-businesscycle models to replicate the behavior of real imports and exports. We extend such a model with Calvostyle price stickiness. We find that the model with producer currency pricing (PCP) for investment goods and local currency pricing (LCP) for durable consumption performs better than the model wit...

This paper proposes an alternative explanation to recurrent hyperinflations other than bounded rationality by explicitly considering the global dynamics of an economy with credit market frictions. In this paper we show that hyperinflations are self-generated and are manifestations of the underlying global dynamic properties of an economy with perfect foresight rational agents that face credit r...

We give sufficient conditions for a non-zero sum discounted stochastic game with compact and convex action spaces and with norm-continuous transition probabilities, but with possibly unbounded state space, to have a Nash equilibrium in homogeneous Markov strategies that depends in a Lipschitz continuous manner on the current state. If the underlying state space is compact this yields the existe...

This paper addresses the large degree of frictional wage dispersion in US data. The standard job matching model without on-the-job search cannot replicate this pattern. With on-the-job search, however, unemployed job searchers are more willing to accept low wage offers since they can continue to seek for better employment opportunities. This explains why observably identical workers may be paid...
