Search frictions and the use of knowledge within firms Link to updated version

I propose a model of the firm, whereby managers and workers match to form firms in a frictional environment. While workers specialize in production, consisting in solving problems that occur and threaten to interrupt projects, managers optimally allocate their time between, on the one hand, starting new projects and searching for new hires, and, on the other, trying to solve problems interrupting current projects, which workers could not solve. Search frictions imply that it takes time to fire workers and replace interrupted projecs with new ones, thus creating a motive for the manager to store and try and resume them using her own knowledge. I show that this intensive margin can account for some puzzling facts concerning firm-level dynamics, namely that wage and productivity on the one hand, and size and output, on the other, can be negatively correlated over time, at the firm level. My model also provides new insights into the sorting outcome between agents, in a stochastic environment with frictions.

Sea trial of the new Datawell GPS directional waverider

Results of the first independent sea trial of the new Datawell GPS systems are presented. Measurements were conducted using a standard Directional Waverider buoy fitted with the new GPS sensors and the traditional accelerometers. This enabled a rigorous comparison with the tried and tested Directional Waverider. The new GPS system performed excellently, giving essentially the same results as the accelerometer sensors. The relative advantages of each measurement system are assessed.
What the customers really want : organie food market in Croatia ?

Organic agriculture in Croatia is still at the beginning of its development. There is no national association of organic producers or nationallaw to regulate the organic production, marketing and control, However, there are several regional organisations that try to facilitate development of organie agriculture, Ouring 1997 Eastern Croatia got the first association of Croatian organic producers named BIOPA. Supported by Friedensbrugg Leimentall and Forschungsinstitut für biologischen Landbau Frick, BIOPA started to organize a small group offarmers who were ready to start with organic production. Organic farming in the Republic of Croatia has marginal importance for national agriculture. There are several reasons for this situation. The market is not yet developed, in general prices are high, buying power very low, agricultural inputs are expensive and farmers have difficulties collecting their accounts receivable. Moreover, absence of know-how for organie agriculture seems to be an important factor, Economic situation in Croatia during the nineties was strongly influenced by several factors: transition from planned to market economy, disintegration of former federal state and breakdown ofexisting market flows together with war from 1991 till 1996. In December 1999, the average familywith three members had 455 Euro l available
Drivers of Performance of Franchisees: A Multi-level Analysis

The aim of this study is to examine the drivers of performance of franchisee organizations. We hypothesize that age, size, obligatory assortment decided by central franchisors, distribution of power from franchisors to franchisees, frequency of franchisor’s visit to franchisee are positively associated with performance of franchisees. The survey data at 186 franchisees are used to test the proposed hypotheses. Principal component analysis and hierarchical linear model are applied in this study. Hierarchical linear model results reveal that whether the proposed hypotheses are statistically supported depending correspondingly on how franchisees’ performance is measured. The paper provides some implications to franchisee literature.
Effect of word of mouth on consumer attitudes and the intention to adopt innovations : A conceptual framework on the moderating role of innovation attributes

Word of mouth (WOM) is a critical factor that influences launch of new products in the market. There is a vast amount of literature on WOM related to WOM sender, but the receiver’s side of WOM needs more analysis. This paper proposes a conceptual model and a number of research propositions that analyzes the influence of a number of WOM dimensions (sender’s similarity, sender’s expertise, valence, and strength) on consumer attitudes towards new products. Consistent with cognitive theories, the link between consumer attitudes, behavioral intention to adopt an innovation, and the actual purchase are discussed. Following, the relationship between consumer attitudes and behavioral intentions is explained as well as the link between intentions and actual purchase decisions, i.e. adoption. A contribution of this paper is to include innovation attributes (relative advantage, compatibility, complexity, trialability, and observability), as moderating variables so the strength between the variables in the working hypotheses can be better understood. Implications for model testing, theory development and managerial issues are discussed. We finally suggest interesting future research avenues.

‘ Enlarging Integration ’ , Regional Convergence , and the Exchange Rate Dynamics

This paper extends Zee’s [1987] two-country OLG model by introducing disparities into Home following from the ‘enlarging integration’ of a less-developed region. It studies the effects of intra-Home convergence on the dynamics of the real exchange rate between Home and Foreign. It is found that in the long run the real exchange rate of enlarged Home depreciates by exactly that percentage by which the domestic population increases. Along the transition towards full convergence the exchange rate and the capital intensity of the less-developed region monotonically increase while the capital intensities of the more developed region and of Foreign temporarily decrease.

Localized social networks, 4. socialization and social mobility in a low-income neighborhood in the Netherlands

The assumed negative effects of living in a low-income neighborhood on the social mobility of already poor residents are central to the current political debate about disadvantaged neighborhoods in the Netherlands. A case study in The Hague addresses the question of which social mechanisms in the daily life of residents might contribute to reduced social mobility in the long run. On the basis of interviews with neighborhood experts and residents about local social networks, job search strategies and work ethics, evidence can be found for limited opportunity structures and negative socialization processes. However, the findings suggest that these mechanisms work more subtly than generally assumed in the research literature, as the specific socio-spatial context also provides opportunities and negative effects are selective rather than generic. introduction 4.1 Social mixing is a key ingredient in urban policy throughout Europe. In the Netherlands, the ideology of social mixing has strongly influenced the current Big Cities Policy which targets the population composition of low-income neighborhoods through physical restructuring of the largely social housing stock. Central to the Big Cities Policy is the idea that neighborhoods should ‘form a safe, healthy and social environment, and not a source of deprivation’ (Ministry of BZK, 2004, p. 19). Social mixing addresses livability, safety and neighborhood management issues in disadvantaged urban neighborhoods (Uitermark, 2003), as well as the unwanted exclusionary consequences of the concentration of poverty for individual residents. Indeed, the Dutch government has expressed strong concerns about the relationship between segregation in the larger cities and faltering social mobility of residents: ‘While the physical and economic infrastructure [of cities] have shown a strong improvement in recent years, the urban social structure continues to be confronted with a concentration of low income households, exclusion, non-participation, health problems, safety issues, and non-integration’ (Ministry of BZK, 2004, p. 17). The foremost focus of social mixing programs is on diversifying the housing stock to accommodate more affluent households, and therefore on achieving a socioeconomic mix, but the debate on mixed neighborhoods is increasingly influenced by the troubled relationship between the segregation and integration of immigrants in Dutch society (Van der Laan Bouma-Doff, 2005; Musterd, 2003).

Lavezzi – Lucio Masserini – Monica Pratesi Resisting the Extortion Racket : an Empirical Analysis

In this paper we study the decision of firms operating in areas where organised crime is pervasive to resist the extortion racket. To this purpose we design a case-control study starting from the unique experience of Addiopizzo (AP), an NGO operating in Palermo (Sicily) which, from 2004, invites firms to resist to the racketeers and join a public list aimed at eliciting critical consumption in favour of firms in the list. We study the determinants of the decision to join AP by estimating a two-level logistic regression model. We find that firm’s total assets and firm’s age have a negative effect on the probability of joining AP, while a higher level of human capital embodied in the firm and a higher number of employees increases such probability. Among the district-level variables, we find that the share of district population reduces the probability to join, while a higher level of socio-economic development, including education levels, increase the probability. We posit that these results support the hypothesis that the decision to join AP is based on a cost-benefit analysis and discuss policy implications of our results.

Ecological-Economic Analysis of Grassland Systems : Resource Dynamics and Management Challenges Kachchh District ( Gujarat )

About 1,400 km of the grasslands in Gujarat are administered by the State Forest Department and are known as vidis. Of the total vidis in the state, a large proportion (92%) is distributed in the semi-arid and arid regions of Saurashtra and Kachchh. About 44 percent of these are in the Kachchh district. Other than these vidis, there are also large grassland tracts that are open for freegrazing. A significantly large population of pastoral and agro-pastoral communities in these arid/semiarid regions sustain their livelihoods based on freegrazing livestock. Most of the grasslands of Kachchh are in the Banni and the Naliya regions (Fig. 1). The grasslands are severely degraded through a combination of intensive grazing, km, of which 80percent is at present invaded by the mesquite, leaving only about 350 km with grass cover. Naliya represents a contiguous grassland tract of nearly 160 km.
The Role of the E-Marketplace as a Marketing Channel for Bed and Breakfast Enterprises in South Africa

The business environment in the bed and breakfast (B&B), tourism and hospitality sector has seen the growth of online trading channels as a mode of e-marketing in various countries, including South Africa (SA). This paper focuses on the role of e-marketplaces in South African (SAn) B&B businesses. The paper discusses challenges often faced by B&Bs in the implementation of e-marketplace processes. The identified challenges include lack of resources, stiff competition from established companies, and the knowledge of how to implement online trading. Recommendations to reduce or eliminate the challenges are presented in the paper, in order to enhance the role of e-marketplaces in South African B&B entities. The researcher observed that e-marketplaces have a fundamental role to play in SMEs, and that more can be tapped from this resource. The research findings will assist in educating B&Bs about e-marketplace marketing and the benefits and opportunities that this phenomenon provides.
Composition and Abundance of Phytoplankton Population in Fish Ponds of Noakhali District , Bangladesh

The study was conducted to explore the phytoplankton composition and abundance in fish ponds of two fish farms named Subarno Agro Based Initiative (SABI) and Bismillah Agro Production (BAP)) located at Noakhali district, Bangladesh. Samples were drawn every week during the entire study period using plankton net (25 ìm mesh size). Phytoplankton enumeration was done on Sedgewick-Rafter counting chamber (S-R cell). Water quality parameters were measured and found within the optimal ranges for phytoplankton productivity. Temperature varied from 25-30 °C; transparency, 25-35 cm; pH, 6.90-8.90; Dissolved Oxygen (DO), 3.70-5.00 mg L ; conductivity, 460-573 ppm and salinity 0 ppt. Four groups of phytoplankton viz.; Bacillariophyceae, 1 Chlorophyceae, Cyanophyceae, Euglenophyceae consisting of 21 genera were identified. Among the identified genera, Euglena, Microcystis and Eurolena were found dominant. Total phytoplankton abundance varied from 36×10 cells/L to 94.92×10 cells/L in the studied ponds. Among the phytoplankton group, Chlorophyceae 5 5 (44.4×10 cells/L) and Euglenophyceae (39.6×10 cells/L) were found most dominant in pond-1 of BAP fish farm. 5 5 In SABI, total phytoplankton densities were found 47.82×10 cells/L and 51×105 cells/L in pond-1 and pond-2 5 respectively while it was recorded 94.92×10 cells/L and 36×10 cells/L respectively in pond-1 and pond-2 of 5 5 BAP. The present study reveals that phytoplankton species and their density are variable among the aquaculture ponds.
A study effect of thyme on Biochemical and Histological changes in Liver of male rats

The increase in the use of thyme in Iraq and in neighboring countries, which may be result in serious side effects necessitate the demand for testing different concentrations of thyme extract(500,750,1000) mg/kg of body weight on rats to be given either by injection or feeding grinded dried thyme leaves added to pellets (50,100,150) g /kg of pellet in of different periods, (10,20,30) days for injection and feeding 2 times weekly. Thyme effects onGOT, GPT and ALP were measured. statistical analysis showed significance significant increase (P≤0.05) in the level of GOT, GPT and decrease in level of ALP in rats treated with 1000 mg of thyme /kg of body weight and 150 g/kg of pellet in 10 days, in 20 days thyme cause highly significance significant increase (P≤0.01) in the level of GOT, GPT and decrease in level of ALP in rats treated with thyme by (750,1000) mg/kg of body weightand (100,150) g/kg of pellet and in 30 days thyme cause significance highly significant increase (P≤0.001) in the level of GOT, GPT and decrease in level of ALP in rats treated with thyme by (500-750–1000) mg/kg of body weight comparing with the negative and positive controls and (50-100–150) g/kg of pellet comparing with the negative control for feeding.
Reactions to Receiving Assumptive Help : The Moderating Effects of Group Membership and Perceived Need for Help 1

The present study examined how group membership and need for help, variables that can operate independently or in combination, can affect reactions to receiving help. Arab participants (n = 164) received or did not receive help from an in-group member (Arab helper) or from an out-group high-status member ( Jewish helper) when the task was described as easy or difficult, or when no information was given. As predicted, Arab participants who received assistance from a Jewish helper or received assistance on an easy task showed more negative reactions than did those who received assistance from an Arab helper or on a difficult task. The theoretical implications for disentangling intergroup and interpersonal influences on reactions to receiving help are considered. jasp_859 2793.2815
Social Undermining , Stress and Well-Being : A Mediation Mechanism

Social undermining of employees has drawn an unprecedented attention of academicians as well as practitioners especially over last couple of decades. The purpose of the study is to explore the effects of social undermining of employee/s thus leading to augmenting the stress level and ultimately affecting negatively the well being of employees working in Banking Sector of Pakistan. Data was drawn from a sample size of 376 respondents selected on the basis of stratified sampling technique. The results proved that social undermining increased stress and caused to reduce the well-being of employees which was in line with the affective event theory. The study was helpful in providing a guideline for researchers working on the role of various mistreatments including social undermining and to better comprehend the mediating nature of stress among said relationship. It also paved the way for new researchers and practioners in working on the multifaceted nature of mistreatments among employees.
1 IT and Productivity : A firm level analysis

In recent years, most industrial economies have witnessed a slowdown in productivity growth. Yet, societies are increasingly transformed by the adaption of information technology (IT). This is believed to increase production efficiency. An important challenge in the literature on returns from IT capital is the measurement of IT. Earlier research often uses data on IT at a high level of aggregation or based on surveys at mostly large companies. In this paper, we use a new and hitherto unexploited data set of all VAT transactions between firms, which allows us to trace IT purchases by firms. We develop a measure of IT capital at the firm level, which improves on earlier ones used in the literature and is available for the entire firm size distribution. Our rich firm level dataset allows us to look at various dimensions of industry and firm level heterogeneity in returns of IT capital. Furthermore we revisit the Solow Paradox and show how much of firm level TFP dispersion is explained by IT. Preliminary and Incomplete.

FLOW-VEGETATION INTERACTIONS : A FIELD STUDY OF RANUNCULUS PENICILLATUS AT THE LARGE PATCH SCALE

Flow-vegetation interactions occur at a wide range of scales, from the sub-leaf to the patch mosaic or river reach scale. At the larger scales, vegetation such as aquatic macrophytes can alter the flow, creating regions of enhanced or reduced turbulence and bed shear stress. This flow alteration can manifest as deposition of fine sediment in the wake region and scour in lateral regions, potentially leading to changes in river morphology. This study focuses on the spatial variation of flow variables around a large macrophyte patch in the River Urie (Scotland). Flow is quantified by a pair of synchronous Nortek Vectrino+ Acoustic Doppler Velocimeters (ADVs), while macrophyte motion is recorded by a synchronous underwater camera system. Preliminary results show reduced mean velocities, but elevated turbulent kinetic energy in the macrophyte wake, with the reduced mean velocities leading to enhanced sedimentation. Reynolds stress distributions indicate flow convergence in the wake as well as evidence of periodic bursting events. This research to experimentally determine the interactions between flow and large macrophyte patches is relevant for a wide range of applications, particularly in streams where high macrophyte densities alter flow and sediment dynamics.
