Large Deviations And The Distribution Of Price Changes, Laurent Calvet, Adlai Fisher, Benoit Mandelbrot Sep 1997

Large Deviations And The Distribution Of Price Changes, Laurent Calvet, Adlai Fisher, Benoit Mandelbrot

Cowles Foundation Discussion Papers

The Multifractal Model of Asset Returns (“MMAR,” see Mandelbrot, Fisher, and Calvet, 1997) proposes a class of multifractal processes for the modelling of financial returns. In that paper, multifractal processes are defined by a scaling law for moments of the processes’ increments over finite time intervals. In the present paper, we discuss the local behavior of multifractal processes. We employ local Hölder exponents, a fundamental concept in real analysis that describes the local scaling properties of a realized path at any point in time. In contrast with the standard models of continuous time finance, multifractal processes contain a multiplicity of …


Multifractality Of Deutschemark/Us Dollar Exchange Rates, Adlai Fisher, Laurent Calvet, Benoit Mandelbrot Sep 1997

Multifractality Of Deutschemark/Us Dollar Exchange Rates, Adlai Fisher, Laurent Calvet, Benoit Mandelbrot

Cowles Foundation Discussion Papers

This paper presents the first empirical investigation of the Multifractal Model of Asset Returns (“MMAR”). The MMAR, developed in Mandelbrot, Fisher, and Calvet (1997), is an alternative to ARCH-type representations for modelling temporal heterogeneity in financial returns. Typically, researchers introduce temporal heterogeneity through time-varying conditional second moments in a discrete time framework. Multifractality introduces a new source of heterogeneity through time-varying local regularity in the price path. The concept of local Hölder exponent describes local regularity. Multifractal processes bridge the gap between locally Gaussian (Itô) diffusions and jump-diffusions by allowing a multiplicity of Hölder exponents. This paper investigates multifractality in …

Simple Counterexample To The Bootstrap, Donald W.K. Andrews Aug 1997

Simple Counterexample To The Bootstrap, Donald W.K. Andrews

Cowles Foundation Discussion Papers

The bootstrap of the maximum likelihood estimator of the mean of a sample of iid normal random variables with mean µ and variance one is not asymptotically correct to first order when the mean is restricted to be nonnegative. The problem occurs when the true value of the mean µ equals zero. This counterexample to the bootstrap generalizes to a wide variety of estimation problems in which the true parameter may be on the boundary of the parameter space. We provide some alternatives to the bootstrap that are asymptotically correct to first order. We consider two types of bootstrap percentile …

Model Selection In Partially Nonstationary Vector Autoregressive Processes With Reduced Rank Structure, John C. Chao, Peter C.B. Phillips Jul 1997

Model Selection In Partially Nonstationary Vector Autoregressive Processes With Reduced Rank Structure, John C. Chao, Peter C.B. Phillips

Cowles Foundation Discussion Papers

The current practice for determining the number of cointegrating vectors, or the cointegrating rank, in a vector autoregression (VAR) requires the investigator to perform a sequence of cointegration tests. However, as was shown in Johansen (1992), this type of sequential procedure does not lead to consistent estimation of the cointegrating rank. Moreover, these methods take as given the correct specification of the lag order of the VAR, though in actual applications the true lag length is rarely known, Simulation studies by Toda and Phillips (1994) and Chao (1993), on the other hand, have shown that test performance of these procedures …

Beyond The Cpi: An Augmented Cost Of Living Index (Acoli), William D. Nordhaus May 1997

Beyond The Cpi: An Augmented Cost Of Living Index (Acoli), William D. Nordhaus

Cowles Foundation Discussion Papers

This note examines the question of calculating an augmented cost of living index (ACOLI). The ACOLI is the appropriate deflator to apply to pretax market incomes when calculating economic well-being. Well-being includes, not only conventional consumer purchases, but also goods and services provided by employers, by mandated social regulations, and by tax-financed public goods. Because such augmented consumption is often provided in ways that raise prices but not market incomes, deflating with conventional price indexes may understate real income growth. An application of the ACOLI approach to the United States during the 1960-1994 period indicates that the conventional consumer price …

Some Higher Order Theory For A Consistent Nonparametric Model Specification Test, Yanqin Fan, Oliver B. Linton Feb 1997

Some Higher Order Theory For A Consistent Nonparametric Model Specification Test, Yanqin Fan, Oliver B. Linton

Cowles Foundation Discussion Papers

We provide second order theory for a smoothing-based model specification test. We derive the asymptotic cumulants and justify an Edgeworth distributional approximation valid to order close to n -1 . This is used to define size-corrected critical values whose null rejection frequency improves on the normal critical values. Our simulations confirm the efficacy of this method in moderate sized samples

The Steady Flow Between Reservoirs With Different Density And Level Through A Contraction, A. Odulo, J. C. Swanson, D. Mendelsohn Jan 1997

The Steady Flow Between Reservoirs With Different Density And Level Through A Contraction, A. Odulo, J. C. Swanson, D. Mendelsohn

Journal of Marine Research

This paper presents a complete analytical solution of steady gravity flow between two reservoirs connected by a channel of slowly varying breadth and containing fluids of different densities and levels. The hydrostatic approximation is used and dissipation is neglected. It is shown that seven different regimes are possible depending on the value of the parameter δ = γ/ε, which is the ratio of relative lighter and denser reservoir level difference, γ, to positive relative density difference, ε. The exact solution of the problem is obtained for all these regimes. If the level of the heavier fluid reservoir is higher than …


Eigenanalysis Of The Two-Dimensional Wind-Driven Ocean Circulation Problem, V. A. Sheremet, G. R. Ierley, V. M. Kamenkovich Jan 1997

Eigenanalysis Of The Two-Dimensional Wind-Driven Ocean Circulation Problem, V. A. Sheremet, G. R. Ierley, V. M. Kamenkovich

Journal of Marine Research

A barotropic model of the wind-driven circulation in the subtropical region of the ocean is considered. A no-slip condition is specified at the coasts and slip at the fluid boundaries. Solutions are governed by two parameters: inertial boundary-layer width; and viscous boundary-layer width. Numerical computations indicate the existence of a wedge-shaped region in this two-dimensional parameter space, where three steady solutions coexist. The structure of the steady solution can be of three types: boundary-layer, recirculation and basin-filling-gyre. Compared to the case with slip conditions (Ierley and Sheremet, 1995) in the no-slip case the wedge-shaped region is displaced to higher Reynolds …


Mechanisms Of Infaunal Polychaete Dispersal And Colonization In An Intertidal Sandflat, David H. Shull Jan 1997

Mechanisms Of Infaunal Polychaete Dispersal And Colonization In An Intertidal Sandflat, David H. Shull

Journal of Marine Research

Changes in benthic infaunal population densities following disturbance may be influenced by colonization mechanisms. Accordingly, this study experimentally examined the relative importance of four colonization mechanisms for seven numerically dominant polychaete species in an intertidal estuarine sandflat in Connecticut, USA. The colonization mechanism an organism used depended upon species characteristics including larval developmental mode and depth distribution within the sediment. A spionid polychaete with planktonic larval development, Polydora cornuta, colonized experimental disturbance treatments primarily by larval settlement. A surface-dwelling syllid polychaete with nonplanktonic development, Streptosyllis arenae, colonized mainly by bedload transport. Two syllid polychaetes developmentally and morphologically similar …


Analysis Of The Mean Annual Cycle Of The Dissolved Oxygen Anomaly In The World Ocean, Raymond G. Najjar, Ralph F. Keeling Jan 1997

Analysis Of The Mean Annual Cycle Of The Dissolved Oxygen Anomaly In The World Ocean, Raymond G. Najjar, Ralph F. Keeling

Journal of Marine Research

A global climatology of the dissolved oxygen anomaly (the excess over saturation) is created with monthly resolution in the upper 500 m of the ocean. The climatology is based on dissolved oxygen, temperature and salinity data archived at the National Oceanographic Data Center. Examination of this climatology reveals statistically significant annual cycles throughout the upper 500 m of the World Ocean, though seasonal variations are most coherent in the North Atlantic, where data density is greatest. Vertical trends in the phase and amplitude of the annual cycle are noted. The cycle in surface waters is characterized by a summer maximum …


Describing Additional Fluxes To Deep Sediment Traps And Water-Column Decay In A Coastal Environment, David A. Timothy, Stephen Pond Jan 1997

Describing Additional Fluxes To Deep Sediment Traps And Water-Column Decay In A Coastal Environment, David A. Timothy, Stephen Pond

Journal of Marine Research

Sediment traps were moored at three stations in Sechelt Inlet, a fjord in southern British Columbia, Canada, for five one-month deployment periods from late January to late June, 1991. On each mooring were traps at three depths; total and constituent fluxes often increased with depth. We present the flux data and describe an analytical model that is based on a set of simultaneous equations for which two unknowns are the decay rate of material representatively caught by two vertically-separated sediment traps and the composition of material causing observed increases in flux with depth. The unknowns are solved in a least-squares …


Estimation Of Vertical Mixing In The Upper Ocean At Station P From Chlorofluorcarbons, R. J. Matear, C. S. Wong Jan 1997

Estimation Of Vertical Mixing In The Upper Ocean At Station P From Chlorofluorcarbons, R. J. Matear, C. S. Wong

Journal of Marine Research

Vertical mixing (Kv) in the upper ocean is estimated from chlorofluorocarbons (CFC's) F-11 and F-12 data collected on 5 cruises (1982, 1985, 1992, 1993, 1995) near Station P (50N, 145W). A one-dimensional advection-diffusion model was fitted to the data from each cruise to estimate vertical mixing (Kv) and upwelling velocity (w). With constant Kv and w, the average value of Kv and w was 0.4 ± 0.1 cm2 s−1 and 1.2 ± 0.4 m yr−1 respectively for the depth range 0–900 m below the base of …


Effect Of A Freshwater Pulse On Mesoscale Circulation And Phytoplankton Distribution In The Lower St. Lawrence Estuary, Claude Savenkoff, Alain F. Vézina, Yves Gratton Jan 1997

Effect Of A Freshwater Pulse On Mesoscale Circulation And Phytoplankton Distribution In The Lower St. Lawrence Estuary, Claude Savenkoff, Alain F. Vézina, Yves Gratton

Journal of Marine Research

As part of a multidisciplinary program to study the physical-biological interactions regulating carbon flows in the lower St. Lawrence Estuary (LSLE), three cruises were conducted in June–July 1990 during a neap-spring tidal cycle when biological production was expected to be maximal. Nutrient (nitrates and silicates), phytoplankton biomass (chlorophyll), oxygen, temperature, salinity, and current fields were used to elucidate the effect of a freshwater pulse produced by the discharge of the St. Lawrence and Saguenay rivers on the current fields and the biological variability and productivity of the LSLE. A simple Rossby adjustment model is presented to explain the temporal (3–5 …


On The Eddy Transfer Of Tracers: Advective Or Diffusive?, Mei-Man Lee, David P. Marshall, Richard G. Williams Jan 1997

On The Eddy Transfer Of Tracers: Advective Or Diffusive?, Mei-Man Lee, David P. Marshall, Richard G. Williams

Journal of Marine Research

Geostrophic eddies have traditionally been viewed within oceanography as diffusing water masses and tracers in a down-gradient manner. However, eddies also have an advective role that may lead to an up-gradient transfer of tracers, as has been recognized in atmospheric tracer studies and recent eddy parameterizations developed for the ocean. Eddies provide an advective transfer or “bolus” velocity through the secondary circulation formed by the slumping of density surfaces in baroclinic instability. Here we use an eddy-resolving isopycnal ocean model to investigate the meridional transfer across a zonal jet. The jet undergoes baroclinic instability, forming a vibrant eddy field and …


Rapid Subduction Of Organic Matter By Maldanid Polychaetes On The North Carolina Slope, L. Levin, N. Blair, D. Demaster, G. Plaia, W. Fornes, C. Martin, C. Thomas Jan 1997

Rapid Subduction Of Organic Matter By Maldanid Polychaetes On The North Carolina Slope, L. Levin, N. Blair, D. Demaster, G. Plaia, W. Fornes, C. Martin, C. Thomas

Journal of Marine Research

In situ tracer experiments conducted on the North Carolina continental slope reveal that tube-building worms (Polychaeta: Maldanidae) can, without ingestion, rapidly subduct freshly deposited, algal carbon (13C-labeled diatoms) and inorganic materials (slope sediment and glass beads) to depths of 10 cm or more in the sediment column. Transport over 1.5 days appears to be nonselective but spatially patchy, creating localized, deep hotspots. As a result of this transport, relatively fresh organic matter becomes available soon after deposition to deep-dwelling microbes and other infauna, and both aerobic and anaerobic processes may be enhanced. Comparison of tracer subduction with estimates …
