Valuation of Mortgage-Backed Securities Based upon a Structural ApproachSpringer Science and Business Media LLC - Tập 8 - Trang 259-289 - 2001
Nobuhiro Nakamura
This paper studies the valuation of mortgage-backed securities (MBS) based upon
a structural approach of several risks involving the prepayment and/or default
behavior of mortgagors. For the Kariya and Kobayashi (1999) model using a
time-consuming Monte-Carlosimulation, we provide an alternative semi-analytic
valuation methodology closely related to solving the (Volterra type) integral
equation wi... hiện toàn bộ
Samuelson Hypothesis & Indian Commodity Derivatives MarketSpringer Science and Business Media LLC - Tập 19 - Trang 331-352 - 2012
Saurabh Kumar Gupta, Prabina Rajib
Samuelson (1965) devised that futures price volatility increases as the futures
contract approaches its expiration. The relation amid the volatility and time to
maturity has significant inference for hedging strategies. Interestingly, so far
the empirical evidence in favor of the Samuelson Hypothesis (maturity effect) is
mixed in various markets. Considering no significant work to examine the
rela... hiện toàn bộ
Optimal Currency Portfolio with Implied Return Distribution in the Mean-Variance ApproachSpringer Science and Business Media LLC - - Trang 1-33 - 2023
Yuta Hibiki, Takuya Kiriu, Norio Hibiki
In this study, we construct an optimal currency portfolio using the implied
return distribution in the mean-variance approach and examine the performance
through a backtest. We estimate the implied expected spot return, implied
volatility, and implied correlation from currency option price data, and propose
a method of constructing a fully forward-looking optimal currency portfolio

The Minimal Entropy Martingale Measures for Exponential Additive ProcessesSpringer Science and Business Media LLC - Tập 16 - Trang 65-95 - 2009
Tsukasa Fujiwara
In this paper, we will consider exponential additive processes as a financial
market model. Under a mild condition, we will determine the minimal entropy
martingale measures (MEMMs) for the exponential additive processes. To this end,
we will prepare several results on the exponential moment of additive processes
and integrals based on them. As an application of our result, we will deduce
optimal ... hiện toàn bộ
The Asian Financial Crisis and Investors’ Risk AversionSpringer Science and Business Media LLC - Tập 13 - Trang 181-205 - 2007
Yasuo Nishiyama
This paper investigates whether changes in U.S. and Japanese banks’ risk
aversion, measured by changes in the relative risk aversion (RRA) coefficient,
are associated with the 1997 Asian financial crisis. It finds that an increase
in U.S. banks’ risk aversion is unambiguously associated with the Asian crisis,
while an increase in Japanese banks’ risk aversion is only weakly associated.
The results... hiện toàn bộ
Inclusions and Exclusions of Stocks in Cross-Border Investments: The Case of Stock ConnectSpringer Science and Business Media LLC - Tập 30 - Trang 701-727 - 2022
Kin Ming Wong, Kwok Ping Tsang
How does the market react when more or fewer investors are allowed to trade
certain stocks? Stock Connect, a cross-border investment channel between
mainland China and Hong Kong, provides a natural testing ground. Investors are
allowed to trade a list of qualified stocks from the stock market on the other
side, and when a stock is removed from the list, investors can only sell but
cannot buy that ... hiện toàn bộ
Speculative Futures Trading under Mean ReversionSpringer Science and Business Media LLC - Tập 23 - Trang 281-304 - 2016
Tim Leung, Jiao Li, Xin Li, Zheng Wang
This paper studies the problem of trading futures with transaction costs when
the underlying spot price is mean-reverting. Specifically, we model the spot
dynamics by the Ornstein–Uhlenbeck, Cox–Ingersoll–Ross, or exponential
Ornstein–Uhlenbeck model. The futures term structure is derived and its
connection to futures price dynamics is examined. For each futures contract, we
describe the evolution... hiện toàn bộ
