Two versions of a vertical product differentiation model, one with fixed and the other variable costs quality, are analyzed to study how hypotheses price versus quantity competition affect equilibrium solutions. Product arises under all scenarios considered, contrasting previous findings symmetric quality choices Cournot behavior. However, relax harsher market competition, firms differentiate more Bertrand than Cournot. A simple welfare measure also indicates that economy is better-off when...
The neutrophil-to-lymphocyte ratio (NLR) is an inflammatory marker predicting the prognosis of several diseases. We aimed to assess its role as a predictor mortality or admission intensive care unit in COVID-19 patients. retrospectively evaluated cohort 411 patients with infection. (NLR), platelet-to-lymphocyte (PLR), and C-reactive protein (CRP) were compared. median age our sample was 72 years (interquartile range: 70−75); 237 males. Hypertension, diabetes ischemic heart disease most...
The authors analyze the effect of economic integration on oligopolists' international trade and foreign direct investment activities, using a three-country, three-firm model. Increased country size leads to dispersed investment, while improved market accessibility export-platform investment. intraregional prompts outside firms invest in regional bloc, reducing product prices, profits intrabloc firms, increasing total surplus. Integrating economies are more likely gain from improving than...
We question the widespread argument that firms embarking on foreign direct investments must possess some specific advantages to offset penalties of operating across national and cultural boundaries. A simple model shows might invest abroad capture local through geographical proximity plant location, rather than exploit existing ones. Because spatially bounded spillovers, laggard use acquire location‐specific knowledge, whereas leading prefer costly exports avoid dissipation their advantages....
Rasmusen et al. (1991) and Segal Whinston (2000) show that an incumbent monopolist might prevent entry of a more efficient competitor by exploiting externalities among buyers. We their results hold only when downstream competition buyers is weak. Under fierce competition, if took place, free buyer would become competitive increase its output profits at the expense sign exclusive deal with incumbent. Anticipating orders from single trigger entry, no will occur. This result robust across...
We propose a simple theory of predatory pricing based on incumbency advantages, scale economies, and sequential buyers (or markets). The prey needs critical to be successful. incumbent predator) has an initial advantage is ready make losses earlier deprive the it needs, thus making monopoly profits later buyers. Several extensions are considered, including cases in which economies exist because demand externalities or two-sided market effects markets characterized by common costs. Conditions...
EU antitrust investigations involve a sequence of events which affect the investigated firm's market value. We model these relationships and estimate their impact on firms' share prices. On average, surprise inspection reduces price by 2.89%, an infringement decision it 3.57%. The C ourt judgments do not have statistically significant effect. Overall, we find that total effect action ranges from −3.03% to −4.55% Fines account for no more than 8.9% this loss, conjecture most loss is due...
