برای شناسایی جمعیت زنبور های عسل ایران نمونه برداری در ماه های بهمن و اسفند 92 از پنج منطقه ایران (شامل شهرهای سنقر ، شیراز، اصفهان، ساری و بیرجند) انجام گرفت. در مورفومتریک استاندارد از ده صفت ظاهری زنبورعسل برای تشخیص جمعیت استفاده شد. این صفات شامل طول بال جلو، عرض بال جلو، زاویه ی a4، زاویه ی d7، زاویه ی g18، طول ترژیت سوم و چهارم ، شاخص کوبیتال، شاخص لاغری، طول خرطوم و طول پا می باشد.همچنی...
The present study aimed to evaluate productive characteristics and the physical, chemical sensory quality of juices elaborated from different genotypes ‘Bordô’ cv. produced in Vale do Rio Peixe-SC region, 2016/17. 11 clones evaluated were identified as: G03, G07, G08, G10, G12, G13, G15, G16, G17, G18 G19. At harvest, fruit production evaluated. mean productivity tested was 31.2 t ha-1, with a ...
This paper studies the efficiency of competitive equilibria in economies where the expansion of investment is facilitated by securitization. We show that the use of securitization is generally associated with constrained inefficient aggregate investment, thereby justifying regulatory intervention in markets for securitized assets. We examine the effectiveness of three policy instruments to addr...
We investigate the effect of a stock market liberalization on industry growth in emerging markets. Consistent with the view that liberalization reduces financing constraints, we find that industries that are more externally dependent and face better growth opportunities grew faster following liberalization. However, this growth increase appears to come from an expansion in the size of existing ...
In standardWalrasian macro-finance models, pecuniary externalities such as fire sales lead to overinvestment in illiquid assets or underprovision of liquidity. We investigate whether imperfect competition (Cournot) improves welfare through internalizing the externality and find that this is far from guaranteed. In a standard model of liquidity shocks, when liquidity is sufficiently scarce, Cour...
We show whether central clearing of a particular class of derivatives lowers counterparty risk. For plausible cases, adding a central clearing counterparty (CCP) for a class of derivatives such as credit default swaps reduces netting efficiency, leading to an increase in average exposure to counterparty default. Further, clearing different classes of derivatives in separate CCPs always increase...
This paper investigates the price adjustment and lead-lag relations between returns on five sizebased portfolios in the Taiwan stock market. It finds evidence that the price adjustment of smallstock portfolios is not slower than that of large-stock portfolios. Additionally, limited evidence supports a positive leading role of large-stock portfolio returns over small-stock portfolio returns. The...
Redistributive Taxation and Personal Bankruptcy in US States Both personal bankruptcy and redistributive taxes can insure households’ consumption risk and both vary considerably across US states. We derive sufficient conditions under which more redistributive taxation makes bankruptcy exemptions less attractive both for the intratemporal insurance and for inter-temporal consumption smoothing. E...
We analyze the equilibrium spread when the transaction size of informed traders is elastic in the value of private information (α). We show that the pooling equilibrium is likely to be inefficient when trade size is sensitive to α and the inefficient equilibrium can occur before the market breaks down. The pooling equilibrium spread does not monotonically increase with α, although it increases ...
