Factor Hoarding and the Propagation of Business Cycles Shocks

This paper analyzes the role of variable capital utilization rates in propagating shocks over the business cycle. To this end we formulate and estimate an equilibrium business cycle model in which cyclical capital utilization rates are viewed as a form of factor hoarding. We find that variable capital utilization rates substantially magnify and propagate the impact of shocks to agents' environments. The strength of these propagation effects is evident in the dynamic response functions of various economy wide aggregates to shocks in agents' environments, in the statistics that we construct to summarize the strength of the propagation mechanisms in the model and in the volatility of exogenous technology shocks needed to explain the observed variability in aggregate U.S. output. Other authors have argued that standard Real Business Cycle (RBC) models fail to account for certain features of the data because they do not embody quantitatively important propagation mechanisms. These features include the observed positive serial correlation in the growth rate of output, the shape of the spectrum of the growth rate of real output and the correlation between the forecastable component of real output and various other economic aggregates. Allowing for variable capital utilization rates substantially improves the ability of the model to account for these features of the data.

Government Finance in the Wake of Currency Crises

Currency crisis, banking crisis, speculative attacks, seigniorage, fiscal reform, bailouts

Hedging and financial fragility in fixed exchange rate regimes

Currency crises that coincide with banking crises tend to share four elements. First, governments provide guarantees to domestic and foreign bank creditors. Second, banks do not hedge their exchange rate risk. Third, there is a lending boom before the crises. Finally, when the currency/banking collapse occurs interest rates rise and there is a persistent decline in output. This paper proposes an explanation for these regularities. We show that government guarantees lower interest rates, and generate an economic boom. But they also lead to a more fragile banking system: banks choose not to hedge exchange rate risk. When the fixed exchange rate is abandoned in favor of a crawling peg banks go bankrupt, the domestic interest rate rises, real wages fall and output declines.Foreign exchange rates ; Hedging (Finance) ; Interest rates

On the fiscal implications of twin crises

This paper explores the implications of different strategies for financing the fiscal cost of twin crises for inflation and depreciation rates. We use a first-generation type model of speculative attacks which has four key features: (i) the crisis is triggered by prospective deficits, (ii) there exists outstanding non-indexed government debt issued prior to the crises; (iii) a portion of the government's liabilities are not indexed to inflation; and (iv) there are nontradable goods and costs of distributing tradable goods, so that purchasing power parity does not hold. We show that the model can account for the high rates of devaluation and moderate rates of inflation often observed in the wake of currency crises. We use our model and the data to interpret the recent currency crises in Mexico and Korea. Our analysis suggest that the Mexican government is likely to pay for the bulk of the fiscal costs of its crisis through seignorage revenues. In contrast, the Korean government is likely to rely more on a combination of implicit and explicit fiscal reforms .Bank failures ; Speculation ; Inflation (Finance)

Prospective deficits and the Asian currency crisis

This paper argues that the recent Southeast Asian currency crisis was caused by large prospective deficits associated with implicit bailout guarantees to failing banking systems. We articulate this view using a simple dynamic general equilibrium model whose key feature is that a speculative attack is inevitable once the present value of future government deficits rises. This is true regardless of the government's foreign reserve position or the initial level of its debt. While the government cannot prevent a speculative attack, it can affect its timing. The longer the delay, the higher inflation will be under flexible exchange rates. We present empirical evidence in support of the three key assumptions in our model: (i) foreign reserves did not play a special role in the timing the attack, (ii) large reserves in the banking sector were associated with large increases in governments' prospective deficits, and (iii) the public knew that banks were in trouble before the currency crises.Financial crises - Asia ; Foreign exchange rates ; Monetary policy ; Money

Capital Utilization and Returns to Scale

This paper studies the implications of procyclical capital utilization rates for inference regarding cyclical movements in labor productivity and the degree of returns to scale. We organize our investigation around five questions that we study using a measure of capital services based on electricity consumption: (1) Is the phenomenon of near or actual short run increasing returns to labor (SRIRL) an artifact of the failure to accurately measure capital utilization rates? (2) Can we find a significant role for capital services in aggregate and industry level production technologies? (3) Is there evidence against the hypothesis of constant returns to scale? (4) Can we reject the notion that the residuals in our estimated production functions represent technology shocks? (5) How does correcting for cyclical variations in capital services affect the statistical properties of estimated aggregate technology shocks? The answer to the first two questions is: yes. The answer to the third and fourth questions is: no. The answer to the fifth question is: a lot.

Report on the Information Retrieval Festival (IRFest2017)

The Information Retrieval Festival took place in April 2017 in Glasgow. The focus of the workshop was to bring together IR researchers from the various Scottish universities and beyond in order to facilitate more awareness, increased interaction and reflection on the status of the field and its future. The program included an industry session, research talks, demos and posters as well as two keynotes. The first keynote was delivered by Prof. Jaana Kekalenien, who provided a historical, critical reflection of realism in Interactive Information Retrieval Experimentation, while the second keynote was delivered by Prof. Maarten de Rijke, who argued for more Artificial Intelligence usage in IR solutions and deployments. The workshop was followed by a "Tour de Scotland" where delegates were taken from Glasgow to Aberdeen for the European Conference in Information Retrieval (ECIR 2017
