A consensus has been reached that the conformation of the anticodon-codon interactions of two adjacent tRNA molecules on the ribosome is a Sundaralingam-type (S-type). Even if it is kept to the S-type, there are still various possibilities. Various experimental data have been supporting an idea that the conformation of A-site tRNA is different from that of P-site tRNA. Those data as well as the...

A field experiment was conducted in the experimental field of Genetics and Plant Breeding Department, Sher-e Bangla Agricultural University, Dhaka, Bangladesh to study variability in 10 F4 lines obtained through intervarietal crosses along with 8 released varieties of Brassica rapa. Significant variation was observed among all the genotypes for all the characters studied. Considering genetic pa...

A sharp increase in the popularity of commodity investing in the past decade has triggered an unprecedented inflow of institutional funds into commodity futures markets. Such financialization of commodities coincided with significant booms and busts in commodity markets, raising concerns of policymakers. In this paper, we explore the effects of financialization in a model that features institut...

Empirical evidence indicates that trades by institutional investors have sizable effects on asset prices, generating phenomena such as index effects, asset-class effects and others. It is difficult to explain such phenomena within standard representative-agent asset pricing models. In this paper, we consider an economy populated by institutional investors alongside standard retail investors. In...

We analyze the entry of new credit rating agencies into structured finance products. Our setting is unique as we study a period in which the incumbents’ reputation was extremely poor and the benefit of more fee income from inflating ratings was low. We find entrants cater to issuers by issuing higher ratings than incumbents, particularly for interest-only (IO) tranches. Ratings by incumbents be...

Ambivalence in the regulatory definition of capital adequacy for credit risk has recently steered the financial services industry to collateral loan obligations (CLOs) as an important balance sheet management tool. CLOs represent a specialised form of Asset-Backed Securitisation (ABS), with investors acquiring a structured claim on the interest proceeds generated from a portfolio of bank loans ...

Since 1996 the Basel risk-weighting regime has been based on the distinction between the trading and the banking book. For a long time credit items have been weighted less strictly if held in the trading book, on the assumption that they are easy to hedge or sell. The Great Financial Crisis made evident that banks declared a trading intent on positions that proved difficult or impossible to sel...

The productivity of the airline industry has increased over time after the deregulation. Longer flights, higher aircraft utilization rates, along with more fuel efficient aircraft, and operational plans designed to economize fuel are major reasons to expect better productivity performance in the airline industry. This achievement cannot be realized unless technological changes in the aircraft m...

The …nancial crisis has raised some concern about the quality of information available on some traded assets on the securities markets to market participants and regulators. Asset-backed securitization in general got partial blame for the paucity of liquidity on bank balance sheets and the consequent credit crunch. After the Asset-Backed Security (ABS) market fell to near inactivity in 2009, th...

We present new evidence that numerous US industries are exposed to exchange rates. The di erences between our ndings and those in the extant literature are a result of using a new methodological approach which takes account of exchange rate regimes based on periods of depreciation and appreciation. Within each regime we show that rst, the stock market's own exposure to exchange rates should be ...
