The Role of Expectation in Job Search and Firm Size Effect on Wages

One of the most puzzling facts in economics is the firm size-wage effect. After controlling for the observable characteristics of workers (age, gender, education, residence etc.), firms (industry, occupation, work conditions etc.) and negotiation effect (unionization), one still finds that the sheer size of a firm increases the wage, contrary to the one-good one-price doctrine. We provide a simple dynamic game model of wage determination to give a new rationale to the firm size-wage effect. We think that the wages are not market clearing prices but strategies by firms. Firms choose wages to control workers' search behavior. The essential feature of the model is that a large firm's history of wages is observable to all the current and future workers, while a small firm is not visible and only its current offer is observable. Therefore a small firm is expected to be a myopic low-wage payer, and its workers search and quit often. A large firm can prevent search if it maintained a high wage throughout the past, thus making workers expect high future wages. In this way, the firm size determines the worker expectations of its future wages, which changes the quit rate and equilibrium wages. To give additional support to our theoretical result, we test a new aspect of firm size-wage effect. Since the effect on wage levels are extensively studied, we derive two main hypotheses on wage gains after job changes. (H1) The proportion of firms that are larger than the previous employer increases the wage gain. (H2) The size of the previous employer decreases the wage gain. The firm size distribution effect (H1) is a new test. We obtain supports for both. Thus we conclude that the wages are strategies and affected by how workers utilize the firm size information in changing jobs. (297 words.)

Back to basics : behavioral theory and internationalization

International business (IB) scholars’ over-reliance on a select few theories leaves our understanding of firm internationalization incomplete. The behavioral theory of the firm (BTF) can offer new insights and can be used to model a broad range of firm actions. We focus on the three basic BTF components: problemistic search, learning by doing, and vicarious learning. These components help us understand why firm behaviors are more dynamic and heterogeneous than other theories allow. BTF, with its emphasis on how firms assess performance according to aspiration levels, selectively learn and update routines, and selectively incorporate the learning of others, is better suited to examine the diversity and change increasingly observed in internationalization decisions. We explain why scholars should move beyond “dynamizing” static theories and show BTF’s applicability to behaviors involving change such as multi-mode market entries and market re-entries. BTF also helps examine the decision to internationalize in the first place, nascent firm internationalization, location choices, international market adaptation, and headquarter–subsidiary relationships. We encourage IB scholars to use theories that can handle the complexity increasingly associated with modern firm growth, and propose BTF as a promising starting point

Rapid development of intestinal cell damage following severe trauma: a prospective observational cohort study

Introduction Loss of intestinal integrity has been implicated as an important contributor to the development of excessive inflammation following severe trauma. Thus far, clinical data concerning the occurrence and significance of intestinal damage after trauma remain scarce. This study investigates whether early intestinal epithelial cell damage occurs in trauma patients and, if present, whether such cell injury is related to shock, injury severity and the subsequent inflammatory response. Methods Prospective observational cohort study in 96 adult trauma patients. Upon arrival at the emergency room (ER) plasma levels of intestinal fatty acid binding protein (i-FABP), a specific marker for damage of differentiated enterocytes, were measured. Factors that potentially influence the development of intestinal cell damage after trauma were determined, including the presence of shock and the extent of abdominal trauma and general injury severity. Furthermore, early plasma levels of i-FABP were related to inflammatory markers interleukin-6 (IL-6), procalcitonin (PCT) and C-reactive protein (CRP). Results Upon arrival at the ER, plasma i-FABP levels were increased compared with healthy volunteers, especially in the presence of shock (P < 0.01). The elevation of i-FABP was related to the extent of abdominal trauma as well as general injury severity (P < 0.05). Circulatory i-FABP concentrations at ER correlated positively with IL-6 and PCT levels at the first day (r2 = 0.19; P < 0.01 and r2 = 0.36; P < 0.001 respectively) and CRP concentrations at the second day after trauma (r2 = 0.25; P < 0.01). Conclusions This study reveals early presence of intestinal epithelial cell damage in trauma patients. The extent of intestinal damage is associated with the presence of shock and injury severity. Early intestinal damage precedes and is related to the subsequent developing inflammatory response

Contrasting perspectives of strategy making: applications in 'Hyper' environments

We revisit the original meaning of turbulence in the socioecological tradition of organization studies and outline a perspective on strategy making grounded in that tradition. This entails a contrast of the socioecological perspective with the more well-known neoclassical perspective on strategy, based on their core decision premises and their different understandings of environmental turbulence. We argue that while some mainstream strategy approaches have taken important strides toward addressing advanced turbulence, many others remain tethered to the neoclassical origins of the strategy discipline and are insufficiently responsive to the new landscape of strategy that now characterizes many industries. This new landscape is construed as the ‘hyper environment’, in which positive feedback processes and emergent field effects produce high volatility. We use two case illustrations from the US healthcare sector to examine how neoclassical and socioecological perspectives contribute to strategizing in hyper environments. Implications for strategic management theory and practice flow from this analysis
