Spatial Integration and Asymmetric Price Transmission in Selected Iranian Chicken Markets
No full textThis study evaluates pattern of price adjustments in selected spatially separated chicken markets in Iran using weekly price data from 1998:17 to 2006:41 including 441 observations in total. The results of Tsay’s test suggest that threshold behavior characterize spatial price linkages among the selected markets that imply on using the threshold models. We use the multi-dimensional (two and three regime) threshold cointegration of TAR and M-TAR models. Our results confirm the different speed of adjustment in response to positive and negative shocks in every case. We also utilize impulse response function to investigate dynamic patterns of adjustments in response to shocks.Spatial Integration, Price Transmission, Threshold Autoregression, Chicken, International Relations/Trade, Marketing,
Unemployment insurance in Algeria : implications for a labor market in transition
No full textTo predict how Algeria's unemployment crisis will evolve, the author evaluates the Algerian unemployment insurance system's ability to finance itself, to affect employment decisions, and promote enterprise restructuring. The main conclusion is that industrial restructuring has serious and persistent implications for the labor market. In an environment where many equilibria are possible, there is a real danger of reaching a high unemployment equilibrium. The big-bang experience of structural adjustment in Central and Eastern Europe transition economies resulted in large-scale unemployment. Despite considerable restructuring progress, structural rigidities still exist in the labor market, and long-term unemployment has persisted. One advantage of the big-bang approach is adjustment speed, but the resulting unemployment may be too costly for Algeria's economy, especially if it persists. A more modern mixed bang approach would incorporate active employment measures to mitigate entrenched unemployment. The policies will maintain or enhance human capital through work, so idle workers don't lose their skills. Flex-time arrangements would help workers maintain an attachment to the labor force. However minor, such work would help workers avoid the traps of long-term unemployment. Two striking conclusions emerge from the Central and Eastern European experience: a) unemployment is not essential to enterprise restructuring and labor market adjustment;and b) growing long-term unemployment is self-fulfilling and results in higher and persistence unemployment. Although active employment measures are costly and have relatively low rates of return in the short run, they can be marginally effective as part of a long-term strategy.Health Economics&Finance,Labor Policies,Environmental Economics&Policies,Labor Markets,Economic Theory&Research,Environmental Economics&Policies,Labor Markets,Economic Theory&Research,Health Economics&Finance,Banks&Banking Reform
<p><strong>Spatial distribution and sampling plan for <em>Tetranychus urticae</em> (Acari: Tetranychidae) in bean crops</strong></p>
No full textThe two-spotted spider mite, Tetranychus urticae Koch, is one of the most destructive bean pests in the central part of Iran. Spider mites feeding on bean leaves cause physiological changes in the plant, which coupled with favorable environmental conditions can lead to increased mite infestations. Significant yield loss can occur in the absence of pest monitoring and timely management. Monitoring for its occurrence and the population density is usually done by visual inspection and consequently demands much effort and time. Hence the objectives of this study were 1) to describe the sampling distribution pattern of this mite and 2) to develop a fixed-precision sequential sampling plan for density estimation. Population estimates were made by registering the number of all stages on 150 leaves of bean plants from mid to the end of July of 2021. Taylor's power law (TPL) was used to analyze the spatial distribution of the pest (r2 = 0.849). Aggregation Indexes (b = 1.239) were significantly greater than one, indicating the aggregation of T. urticae. We used TPL parameters to develop a sequential sampling plan at precision levels of 0.10 and 0.25 using Green's method. Fixed-precision sequential sampling plan could represent a suitable method for sampling T. urticae population in bean fields in the Varamin area, with the practical advantage of lower cost and time consumption than standard sampling plans. The use of this plan outside the Varamin area can be applicable. In conclusion, the sequential sampling plans determined in this study for mites can be incorporated into integrated pest management programs in bean crops by making precise and quick decisions
Corporate communication as a governance mechanism: A content analysis of corporate public disclosures
No full textCorporate communication efforts have mainly been viewed as a by-product of governmental regulations and board of directors’ oversight. In this paper, we examine the role of corporate communication as a stand-alone governance mechanism. We introduce a new business-related dictionary and conduct automated textual analysis of over 150,000 electronic documents filed by a sample of firms listed on the S&P/TSX Composite Index from 1999 to the end of 2014. Our findings demonstrate the governing role of corporate communication by documenting the adverse market effects of deviations from the expected level of communication. Moreover, as a governance mechanism, corporate communication shows substitution/complementary relationships with other established governance mechanisms. In addition, we find a non-linear relationship between a firm’s communication efforts and its value and risk levels. Results are robust after controlling for major corporate events (M&A, spin-offs, financial distress and bankruptcy, and significant lawsuits). These findings contribute to corporate governance literature and the understanding of agency theory predictions of communications and disclosures’ economic effects
