Firms' pattern of trade and access to finance.

This paper summarizes recent advances in the empirical research on firms' learning from trade participation and the role of finance in both starting to trade, surviving in export markets as well as expanding along the intensive and extensive trade margins. It highlights the increased importance of imports, which impacts at firms' performance primarily through relaxed technological constraints by increasing firms's scope of inputs and by lowering their input price index. In addition, imports are shown to boost firms' innovation and introduction of new products, which facilitates firms' decisions to start exporting. Another important aspect that has been highlighted is the essential role of finance in furthering firms'survival and expansion in export markets.exports,learning-by-exports,export expansion, financial constraints, credit crunch;

Measuring the Values for Time

Most economic models for time allocation ignore constraints on what people can actually do with their time. Economists recently have emphasized the importance of considering prior consumption commitments that constrain behavior. This research develops a new model for time valuation that uses time commitments to distinguish consumers' choice margins and the different values of time these imply. The model is estimated using a new survey that elicits revealed and stated preference data on household time allocation. The empirical results support the framework and find an increasing marginal opportunity cost of time as longer time blocks are used.

Shaping and reshaping the work organisation : including or excluding low skilled labour? The case of the nurse assistant in Germany, France and the United Kingdom

The hospital industry could be characterised on the one hand as under “industrial constraints” (just in time, 24 hours opening, and on the other hand as a service activity with, in departments, a high degree of patient oriented activities. Very similar pressure are exerted on hospitals in the three countries (UK, G and F): budget constraints and a trend to “quasi market” regulations (cf. Bartlett/LeGrand 1993); changes in the competitive structure linked with the increasing importance of private hospitals; a new demand for care arising from the ageing population and more complex diseases; new rules to control for the quality of care. Despite these similarities between the external demands and constraints, the organisation of care work and the division of labour remains very different between the countries. Section 1 presents a brief historical perspective of the nurse assistant in the three countries and the major contrast regarding the level and trends of employment. Section 2 analyses the training profiles and access to training. Section 3 describes the tasks performed and draws the job profile of a NA. Section 4 discusses the wage levels and structure and section 5 patterns of mobility.Low wage; Nurse assistant; Hospital; Division of labour; Comparison; Germany; France; the United Kingdom

Engaging and empowering first-year students through curriculum design: perspectives from the literature

There is an increasing value being placed on engaging and empowering first-year students and first-year curriculum design is a key driver and opportunity to ensure early enculturation into successful learning at university. This paper summarises the literature on first-year curriculum design linked to student engagement and empowerment. We present conceptualisations of ‘curriculum’ and examples from first-year curriculum design. We also note the limited literature where students have been involved in designing first-year curricula. The results of the literature review suggest that key characteristics of engaging first-year curricula include active learning, timely feedback, relevance and challenge. The literature also points to the importance of identifying students' abilities on entry to university as well as being clear about desired graduate attributes and developmental goals. Acknowledging realities and constraints, we present a framework for the first-year curriculum design process based on the literature

Firm investment in imperfect capital markets: A structural estimation

We set up a dynamic model of firm investment in which liquidity constraints enter explicity into the firm's maximization problem. The optimal policy rules are incorporated into a maximum likelihood procedure which estimates the structural parameters of the model. Investment is positively related to the firm's internal financial position when the firm is relatively poor. This relationship disappears for wealthy firms, which can reach their desired level of investment. Borrowing is an increasing function of financial position for poor firms. This relationship is reversed as a firm's financial position improves, and large firms hold little debt. Liquidity constrained firms may be unused credits lines and the capacity to invest further if they desire. However the fear that liquidity constraints will become binding in the future induces them to invest only when internal resources increase. We estimate the structural parameters of the model and use them to quantify the importance of liquidity constraints on firms' investment. We find that liquidity constraints matter significantly for the investment decisions of firms. If firms can finance investment by issuing fresh equity, rather than with internal funds or debt, average capital stock is almost 35% higher over a period of 20 years. Transitory shocks to internal funds have a sustained effect on the capital stock. This effect lasts for several periods and is more persistent for small firms than for large firms. A 10% negative shock to firm fundamentals reduces the capital stock of firms which face liquidity constraints by almost 8% over a period as opposed to only 3.5% for firms which do not face these constraints.Investment, liquidity constraints, Tobin's q, estimation of dynamic structural models, financial accelerator

EU Environmental Policy and Competitiveness

Protection of the environment was not a specific importance to the Community although the Treaty of Rome expressly specified that "health, safety, environmental protection" shall be based on "a high level of protection". In deciding upon a framework for a European environmental policy, the Community was also responding to increased public awareness of the problem and concerns about the state of the natural and man-made environment. During the past years, competitiveness concerns have dominated the EU policy debate, in the course of which a growing consensus is being developed on the importance of eco-innovations and resource efficiency for EU competitiveness and on the market opportunities they offer. There is increasing evidence that environmental policy and eco-innovations can promote economic growth, as well as maintain and create jobs, contributing both to competitiveness and employment. Environmental constraints to rapid economic growth are increasingly recognized by countries, leading to a rising awareness of the need for sustainable development. Implementation of an environmental policy, however, generates significant implications for competition among countries.EU Environmental policy, Competitiveness, Pollution control, Sustainable development, Resource efficiency

Patriarchy and Women's Agricultural Production in Rural Nigeria

The crucial importance of women's contribution to food security in developing countries like Nigeria cannot be over emphasized. It is estimated that about 80% of women in rural areas are engaged in food crops production. Rural women are regarded as the mainstay of small scale agriculture. In most developing countries such as Nigeria, the concern for increasing women's economic participation especially in food production can be seen within the wider general concern to alleviate the economic conditions of the poor households, esp cially those in the rural sector, majority ofwhom are-women and who occupy lower socioeconomic status compared to their male counterparts. Nigeria is a patriarchal society and inheritance is patrilineal which invariably--creates severe cultural inhibitions to the aspiration and productive capacity of women. This paper therefore discusses the constraints faced by women in Nigeria as producers and income earners for their families by focusing on women's burden of reproduction, decision making power, access to and ownership of land, capital, information and technology. In discussing this, it is recognized that both women and men are an integral part of the solution to increasing agricultural productivity and improving household food security and nutrition

A novel cost effective and high-throughput isolation and identification method for marine microalgae

Background: Marine microalgae are of major ecologic and emerging economic importance. Biotechnological screening schemes of microalgae for specific traits and laboratory experiments to advance our knowledge on algal biology and evolution strongly benefit from culture collections reflecting a maximum of the natural inter- and intraspecific diversity. However, standard procedures for strain isolation and identification, namely DNA extraction, purification, amplification, sequencing and taxonomic identification still include considerable constraints increasing the time required to establish new cultures. Results: In this study, we report a cost effective and high-throughput isolation and identification method for marine microalgae. The throughput was increased by applying strain isolation on plates and taxonomic identification by direct PCR (dPCR) of phylogenetic marker genes in combination with a novel sequencing electropherogram based screening method to assess the taxonomic diversity and identity of the isolated cultures. For validation of the effectiveness of this approach, we isolated and identified a range of unialgal cultures from natural phytoplankton communities sampled in the Arctic Ocean. These cultures include the isolate of a novel marine Chlorophyceae strain among several different diatoms. Conclusions: We provide an efficient and effective approach leading from natural phytoplankton communities to isolated and taxonomically identified algal strains in only a few weeks. Validated with sensitive Arctic phytoplankton, this approach overcomes the constraints of standard molecular characterisation and establishment of unialgal cultures

An Empirical Study on the Relationship between Entrepreneur’s Reputation and Financing Constraints

Information asymmetry is an important reason that causes external financing constraints. Because reputation has the function of signal transmission, a better reputation of an entrepreneur can reduce the degree of the firm information asymmetry and alleviate financing constraints of the firm. Based on the grouped sample of 94 listed companies of China from 2007 to 2009, this paper did empirical study on the relationship between entrepreneur’s reputation and financing constraints. The results show that entrepreneur’s reputation has a significant effect on firm financing activity. In other words, higher entrepreneur’s reputation leads to lower financing constraints. This study has a significant impact in helping managers and investors realize the importance of signaling effect of a good reputation in capital market. Meanwhile, it helps motivate entrepreneurs to establish good reputation, increasing the efficiency of capital market
