The common transport policy of the EEC

A free market in the sphere of transport is to be established in the European Community by 1992. What conditions prevail today in this sector and what steps must be taken in order to establish a workable Common Transport Market?     

INPUTS,OUTPUTS AND PRODUCTIVITY CHANGE IN THE AUSTRALIAN SHEEP INDUSTRY

Tornqvist quantity indexes of output and input are computed for the period 1952/53 to 1976/77 from Australian Sheep Industry Survey data. The computation includes estimating the annual service flow from durable inputs. Total productivity in the sheep industry is estimated to have increased by 2.9 per cent per annum during this 25-year period. While the ratio of capital employed per unit of labour has increased, materials, services and livestock have been the inputs for which the quantity used has increased most rapidly. On the output side, there has been a move towards greater diversification with both crop and cattle enterprises on 'sheep properties' increasing in relative importance.     

FROM EXPERIENCE: Balancing the Product Development Process: Achieving Product and Cycle-Time Excellence in High-Technology Industries

Most companies' product development process (PDP) is inefficient and slow. Consequently, products are often late-to-market, over cost and not well-aligned with customer's needs. Because it involves all levels of the organization and crosses all functional boundaries, the PDP is very difficult to control. Unbalanced control is at the root of many of the symptoms of a troubled PDP. Michael T. Anthony and Jonathan McKay investigate the four primary unbalanced PDP behaviors exhibited by organizations and present four balancing mechanisms to correct these flaws. In their view, a balanced PDP contains a structured development methodology and project reviews at specific, high-impact points that involves top management appropriately while still allowing empowerment of the project teams.     

How does working capital management affect the profitability of Spanish SMEs?

This paper analyzes the relation between working capital management and profitability for small and medium-sized enterprises (SMEs) by controlling for unobservable heterogeneity and possible endogeneity. Unlike previous studies, we examine a non-linear relation between these two variables. Our results show that there is a non-monotonic (concave) relationship between working capital level and firm profitability, which indicates that SMEs have an optimal working capital level that maximizes their profitability. In addition, a robustness check of our results confirms that firms?? profitability decreases as they move away from their optimal level.     

The impact of individualism on buyer–supplier relationship norms,trust and market performance: An analysis of data from Brazil and the U.S.A.

This study focuses on the impact of the cultural dimension of individualism, face-to-face communication and the effect of relational norms such as supplier involvement and trust on the market performance of buyer firms. We use the culture literature and social exchange theory to test hypotheses using a sample of Brazilian and US manufacturing firms. The data were analyzed using variance-based structural equation modeling, employing nonlinear partial least squares regression. Our findings indicate that individualism is negatively related to the involvement of suppliers in the production process but is not associated with trust in suppliers. In addition face-to-face communication seems to have a positive effect on supplier involvement and trust.     

Risk and the cross section of stock returns

This paper mathematically transforms unobservable rational expectation equilibrium model parameters (information precision and supply uncertainty) into a single variable that is correlated with expected returns and that can be estimated with recently observed data. Our variable can be used to explain the cross section of returns in theoretical, numerical, and empirical analyses. Using Center for Research in Security Prices data, we show that a −1σ$-1\sigma$ to +1σ$+1\sigma$ change in our variable is associated with a 0.31% difference in average returns the following month (equaling 3.78% per annum). The results are statistically significant at the 1% level. Our results remain economically and statistically significant after controlling for stocks' market capitalizations, book-to-market ratios, liquidities, and the probabilities of information-based trading.     

Earnings conference calls and stock returns: The incremental informativeness of textual tone

Quarterly earnings conference calls are becoming a more pervasive tool for corporate disclosure. However, the extent to which the market embeds information contained in the tone (i.e. sentiment) of conference call wording is unknown. Using computer aided content analysis, we examine the incremental informativeness of quarterly earnings conference calls and the corresponding market reaction. We find that conference call linguistic tone is a significant predictor of abnormal returns and trading volume. Furthermore, conference call tone dominates earnings surprises over the 60 trading days following the call. The question and answer portion of the call has incremental explanatory power for the post-earnings-announcement drift and this significance is primarily concentrated in firms that do not pay dividends, illustrating differences in investor behavior based on the level of cash flow uncertainty. Additionally, we find that a context specific linguistic dictionary is more powerful than a more widely used general dictionary (Harvard IV-4 Psychosocial).     

China as a Global Manufacturing Powerhouse： Strategic Considerations and Structural Adjustment

This study examines the nature and consequences of China＇s rise to the center of world economic affairs through manufacturing-led development. Our historical analysis shows that China is still well short of the point in its developmental process where its growth might be reasonably expected to slow, or the energy, resource and carbon intensity of growth to recede. The study argues that the current trajectory of industrialization will have to be altered when China becomes more actively engaged in dealing with structural issues at home and abroad against the background of the unwinding of global imbalances. One profitable strategy that China might employ wouM be to approximate the incredibly fruitful mass-market integration efforts of the USA that eventually elevated it to its position of global primacy. The cyclical re-emergence of excess capacity in Chinese heavy industry, serious questions about the medium term ability of other major regions to accommodate further large gains in Chinese market share, and the stark conflict between the contemporary style of industrial development and the health of the biosphere indicate strongly that now is the time to catalyze the required adjustment and reform processes that will underpin sustainable long-run prosperity.     

The impact of German-speaking online media on tourist arrivals in popular tourist destinations for Europeans

This empirical study analyzes the relationship between the sentiments in online media with regard to travel destinations and corresponding tourist arrivals. We expect the media reports on political and economic instability and turmoil to enhance tourist arrival nowcasts and forecasts, as they can probably complement them with information on disruptions and shocks. Therefore, we believe this research will help to build better models for tourism demand nowcasting and forecasting. We use the sentiment in the German-speaking online media because the German-speaking region is the most populated in Europe and has the largest group of travelers visiting destinations in and around Europe.

An artificial neural network is used to analyze the mood of the media. The software classifies news items regarding potential tourist destinations with either positive or negative labels. The number of positive and negative news items is used to build sentiment indices for popular tourist destinations for Europeans.

Our results show strong correlations between the mood concerning tourist destinations and tourist arrivals in these countries. Indeed, disruptions and shocks prevalent in the news are reflected in similar ratios in both tourist arrivals and sentiment indices. These results can be used as a new explanatory variable for tourism demand modelling.     

The influence of seller learning and time constraints on sequential bargaining in an artificial perishable goods market

This paper investigates the formation of prices in a perishable goods market where agents bargain repeatedly through pair-wise interactions. After extensive field observations, we chose to focus on two aspects that seem important to actors of this market: the passage of time and update in judgement when gathering information. The main feature of the market is that a seller bargaining with a buyer has incomplete information about buyer's willingness to pay and is not sure how her trading partner will evaluate an offer or compare it with other options. On the other hand, buyers have limited time to look for goods and cannot meet all possible sellers before making a decision. Hence agents cannot calculate the best price to offer but receive information through limited interactions, and use this information to choose their actions.An agent-based model was built to represent a framework that mimics the observed market institution and where agent's possible behaviors and learning was made as consistent as possible with gathered data. Simulations were run, first for sensitivity analysis concerning main parameters, then to test the dependance of agents’ learning to (a) the time buyers can spend on the market and (b) the frequency of update in learning by sellers. To validate the model, features produced by the simulated market are compared to the stylized facts gathered for negotiation about four goods. We reproduce the main features of the data on the dynamics of offers, transaction prices and agents’ behavior during the bargaining phases.
