Cultural change that sticks

When a major change initiative runs aground, leaders often blame their company's culture for pushing it off course. They try to forge ahead by overhauling the culture--a tactic that tends to fizzle, fail, or backfire. Most cultures are too well entrenched to be jettisoned. The secret is to stop fighting your culture--and to work with and within it, until it evolves in the right direction. Today's best-performing companies, such as Southwest Airlines, Apple, and the Four Seasons, understand this, say the authors, three consultants from Booz & Company. These organizations follow five principles for making the most of their cultures: 1. Match strategy to culture. Culture trumps strategy every time, no matter how brilliant the plan, so the two need to be in alignment. 2. Focus on a few critical shifts in behavior. Wholesale change is hard; choose your battles wisely. 3. Honor the strengths of the existing culture. Every culture is the product of good intentions and has strengths; put them to use. 4. Integrate formal and informal interventions. Don't just implement new rules and processes; identify "influencers" who can bring other employees along. 5. Measure and monitor cultural evolution. Otherwise you can't identify backsliding or correct course. When the leaders of Aetna applied these rules while implementing a new strategy in the early 2000s, they reinvigorated the company's ailing culture and restored employee pride. That shift was reflected in the business results, as Aetna went from a $300 million loss to a $1.7 billion gain.

Technological paradigms,innovative behavior and the formation of dissipative enterprises

Although many studies have assigned a key role to technological paradigms in the development and diffusion of new technologies, which are often pioneered and led by small businesses, the nature of this term has remained somewhat unclear. This paper uses concepts from modern theories of chaos, information theory and dissipative structures, to describe the process through which new technological paradigms form and how the evolve. This analysis shows that the development of a new and innovative product or production methods drive existing as well as new firms to search for innovations. The interaction of all firms that are affected by this explorative behavior generates escalating waves of change and thereby creates chaos, which is the source of the materials from which new technological structures emerge. These new structures are arrangements of production tasks and activities that link an extended, interindustry group of firms into an interdependent system. This structure constitutes a technological paradigm when it serves as a matrix, or template, through which all firms in the system engage in innovative activity.     

Boon or bane? Others' unemployment,well-being and job insecurity

The social norm of unemployment suggests that aggregate unemployment reduces the well-being of the employed, but has a far smaller effect on the unemployed. We use German panel data to reproduce this standard result, but then suggest that the appropriate distinction may not be between employment and unemployment, but rather between higher and lower levels of labour-market security, at least for men. Men with good job prospects, both employed and unemployed, are strongly negatively affected by regional unemployment. However, insecure employed men and poor-prospect unemployed men are less negatively, or even positively, affected. There is however no clear relationship for women. We analyse labour-market inequality and unemployment hysteresis in the light of our results.     

Improving access to health facilities in Nouna district,Burkina Faso

The Nouna health district in Burkina Faso, has a population of approximately 275,000 people living in 281 villages, and is served by 25 health facilities, as of 2006. For many people, the time and effort required in traveling to a health facility, which may demand a journey of many kilometers over poor roads on foot, is a deterrent to seeking proper medical care. In this study we examine how access to health facilities in Nouna may be improved by considering the configuration of the road network in addition to the locations of the facilities. We model the situation as a facility location–network design problem and draw conclusions about how best to improve the physical access of the health facilities. Our model shows the extent to which access can be improved when the road network is considered along with facility locations, in contrast to facility locations considered alone.     

Playing Cournot although they shouldn’t

Summary. In this note, we experimentally investigate the extended game with action commitment in a Cournot duopoly with asymmetric cost. Risk dominance considerations allow to select a unique equilibrium in which the low-cost firm is the Stackelberg leader. The data, however, do not support the theory as simultaneous-move play is modal. Average output choices are in line with the Cournot equilibrium. This suggests that Cournot is a much more robust predictor for competition in markets than theory suggests.Received: 14 October 2002, Revised: 1 December 2003, JEL Classification Numbers: C72, C92, D43.

Common stock returns in the pre-WWI Berlin Stock Exchange

We provide new evidence on the efficiency of the Berlin Stock Exchange prior to World War I, when it ranked among the top few markets worldwide by market capitalization. Using a new set of monthly stock price data for a random sample of German companies between 1904 and 1910, we estimate a typical three-factor model and find that returns relate positively to risk (beta), but that book-to-market ratios enter as well (negatively). Firm size and earnings/price ratio relate positively but weakly to returns. The results indicate that the Berlin market did not suffer from unusually large pricing anomalies; thus, its performance was not substantially different from modern markets. Also supporting the conclusion of market efficiency, a momentum portfolio earns returns not different from zero, on average.
