A LONG-RUN INTERPRETATION OF REGIONAL INPUT-OUTPUT ANALYSIS*

ABSTRACT. Regional input-output (I-O) analysis is traditionally motivated by a short-run, extreme Keynesian vision of markets. In this paper we argue that an appropriately formulated, investment-endogenous, I-O system replicates the long-run equilibria of a wide range of regional models, many of which do not operate as I-O systems in the short run. In particular, we use a computable general equilibrium (CGE) framework to illustrate the impact of an aggregate demand disturbance on an I-O and standard neoclassical model. When run forward over a number of periods, the results from the capacity-constrained neoclassical model asymptotically approach the I-O outcome. We use sensitivity analysis to examine the speed of adjustment of the neo-classical system and investigate barriers to the attainment of the I-O result.     

SUFFICIENT CONDITIONS FOR NEGATIVE EXPONENTIAL DENSITIES A FURTHER ANALYSIS

ABSTRACT Brueckner correctly pointed out that one of the sufficient conditions for negative exponential densities is a unitary price elasticity of the compensated, not the uncompensated, demand for housing. This note shows that the Brueckner condition implies a zero income elasticity of housing demand when income and price elasticities are constrained to be constants. It also derives the utility function that gives rise to negative exponential densities in this case, given that other standard assumptions are satisfied. In light of empirical evidence, justification for the popular negative exponential functional form seems rather weak.     

Geometry‐coupled reactive fluid transport at the fracture scale: application to CO2 geologic storage

Water acidification follows CO₂ injection and leads to reactive fluid transport through pores and rock fractures, with potential implications to reservoirs and wells in CO₂ geologic storage and enhanced oil recovery. Kinetic rate laws for dissolution reactions in calcite and anorthite are combined with the Navier‐Stokes law and advection–diffusion transport to perform geometry‐coupled numerical simulations in order to study the evolution of chemical reactions, species concentration, and fracture morphology. Results are summarized as a function of two dimensionless parameters: the Damköhler number Da which is the ratio between advection and reaction times, and the transverse Peclet number Pe defined as the ratio between the time for diffusion across the fracture and the time for advection along the fracture. Reactant species are readily consumed near the inlet in a carbonate reservoir when the flow velocity is low (low transverse Peclet number and Da > 10^?1). At high flow velocities, diffusion fails to homogenize the concentration field across the fracture (high transverse Peclet number Pe > 10^?1). When the reaction rate is low as in anorthite reservoirs (Da < 10^?1), reactant species are more readily transported toward the outlet. At a given Peclet number, a lower Damköhler number causes the flow channel to experience a more uniform aperture enlargement along the length of the fracture. When the length‐to‐aperture ratio is sufficiently large, say l/d > 30, the system response resembles the solution for 1D reactive fluid transport. A decreased length‐to‐aperture ratio slows the diffusive transport of reactant species to the mineral fracture surface, and analyses of fracture networks must take into consideration both the length and slenderness of individual fractures in addition to Pe and Da numbers.     

Routes of Resistance: Mobilizing Discourses of Opportunity in Ann Petry’s The Street and Austin Clarke’s The Meeting Point

Ann Petry’s The Street and Austin Clarke’s The Meeting Point provide important representations and affirmations of black people’s use of movements such as educational attainment and economic advancement to create routes to resist inequitable treatment and demand equal access to the benefits of belonging to American and Canadian national communities. In The Street, Lutie employs intellectual and economic movements to achieve her American dream but learns that systematic inhibitions block her intended ascension. In The Meeting Point, Bernice also tries to attain education and make financial strides to achieve her Canadian dream but finds herself barred from fully materializing that dream. Lutie and Bernice continue their quests to fulfill their mobility ideals, despite obstructions they face. Through that movement, which is driven by their knowledge of the implications of their exclusions from promises of the nations they call home, they counter boundaries intended to restrict them. While they do not accomplish fully their upward mobility ideals, their resistance demonstrates their refusal to be denied the benefits of American and Canadian discourses of opportunity. Petry’s and Clarke’s representations of this persistent resistance help inform and give voice to struggles against exclusionary practices blacks in the United States and Canada continually experience.     

North Korea’s Response to US Army Propaganda Leaflets during the Korean War

This study examines a particular aspect of the history of North and South Korea’s bbira (propaganda leaflets), focusing on North Korea’s propaganda strategies in response to US propaganda during the Korean War, including perceptions of propaganda leaflets targeting North Koreans and counterstrategies used against them. The research herein analyses Munhakyesul, the leaflets during the Korean War, and the leaflets held by the DMZ Museum. The findings of this study reveal characteristics of and differences between the psychological tactics used by North Korea and the US during the Korean War, as exhibited through the use of these propaganda leaflets.     

Pierre-Antoine Antonelle and representative democracy in the French Revolution

This article examines the political thought of Pierre-Antoine Antonelle, a prominent democrat during the French Revolution. In pamphlets and newspaper articles between 1795 and 1799 he put forth an elaborate theory of ‘representative democracy’ which was a novel and radical vision of political reform and republican international order. His political and economic plan for a democratic future was focused on conceptualizing a realistic transition path to a genuinely republican society. In the wake of historians who pointed out the existence and importance of the idea of ‘representative democracy’ during the Directory, this article delves into the content of this idea by placing it in the context of Antonelle and his fellow travellers’ political struggle to consolidate the Republic while avoiding both anarchy and aristocracy.
