Cardiac dysfunction is a common complication of sepsis in individuals with preexisting coronary disease and portends a poor prognosis when progressing to ischemic cardiogenic shock. In this setting, maximal medical therapy in isolation is often inadequate to maintain cardiac output for patients who are poor candidates for immediate revascularization. Furthermore, the use of vasopressors and ino...

In 2010, Steve Jobs announced that Apple would no longer support Adobe Flash, an at-the-time popular set of tools for creating Internet applications. In the years following Jobs’ announcement, the use of Flash declined precipitously. Using data from an online labor market, we study how the market for Flash skills evolved and how Flash programmers fared. The large negative shock in the demand fo...

We revisit the discussion about the relationship between price’s cyclical features, implicit collusion and the demand level in an oligopoly supergame where a positive shock may hit demand and disrupt collusion. The novel feature of our model consists in characterising the post-shock noncooperative price and comparing it against the cartel price played in the last period of the collusive path, t...

This paper uses a quantile impulse response approach to investigate the impact of oil price shocks on Chinese stock returns. This process allows us to uncover asymmetric effects of oil price shocks on stock market returns by taking into account the different quantiles of oil price shocks. Our results show that the responses of Chinese stock market returns to oil price shocks differ greatly, dep...

We show that vertical integration decisions of managers may affect adversely consumers even in the absence of monopoly power in either supply or product markets. This effect is most likely to come about when demand is initially high and there is a negative supply shock or when demand is low and there is a positive demand shock. The results are robust to the introduction of active shareholders a...

We consider a dynamic asset pricing model with one asset, in which one informed trader trades against liquidity traders and competitive market makers. Informed trader has private information about the fundamental value of the asset as well as the exogenous demand shock on the market. We characterize the unique linear Markov equilibrium of the model. With just the private information about funda...

Characterization and evaluation of a biological submerged filter was carried out on a full-scale pilot plant performing removal of biochemical oxygen demand (BOD) and total nitrogen (TN) from pre-treated urban wastewater. The average influent values of BOD5, chemical oxygen demand (COD) and TN were 370, 1,015 and 60 mg/L, respectively. The pilot plant produced good discharge quality during stea...

I ran’s economy is suffering from sharp and persistent economic shocks and agriculture plays an undeniable role in its economic growth and development. The aim of this paper is to study the relative contributions of various macroeconomic shocks to generating fluctuations in Iran’s agriculture sector. To do so, a Dynamic Stochastic General Equilibrium (DSGE) model, emphasizing on the ...

We provide a comprehensive analysis of capacity investment decisions in duopoly models with demand uncertainty. Firms make capacity investment, production, delivery and pricing decisions. Capacity investment decisions are always made ex-ante demand whereas price decisions always ex-post. The interplay between the timing of demand information and the decision of production and delivery endows fi...
