Estimates of costs and revenues for steamboating in the Louisville-New Orleans trade indicate that after the 1820's the steamboat transport market experienced the long–run equilibrium characteristic of purely competitive industries.

Long Run Equilibrium

AbstractThe Indian exchange rate system has evolved from a pegged system to the current managed float. The study examines the presence of a long-run equilibrium in the monthly Indian exchange rate (Rs/USD) using a current account monetary model (or flexible price monetary model) while accounting for different nonlinearities over the period January 1993 to January 2014 (pre-inflation targeting period). The nonlinear adjustment to disequilibria is modelled using a nonlinear error correction model (NLECM). The nonlinear current account monetarism (CAM) model includes nonlinear transformations of long-run dynamics in the ECM to account for different nonlinearities: multiple equilibria (cubic polynomial function), nonlinear mean reversion (rational polynomial function), and smooth and gradual regime switches (exponential smooth transition autoregressive (ESTAR) function). The NLECM-ESTAR model outperforms other alternatives based on model and forecast performance measures, implying the existence of nonlinear mean reversion and smooth transition across different periods of overvaluation and undervaluation of the exchange rate. This implies the presence of asymmetric adjustment to the movements from the long-run equilibrium, but the nature of such transitions is smooth and not abrupt. The paper also establishes the uniqueness of the long-run equilibrium. A comparison to the sticky price monetary model could not be made due to stationary exchange rate disequilibrium.

Long Run Equilibrium

This paper incorporates human capital accumulation through provision of universal public education by a balanced-budget government to a demand-driven analytical framework of functional distribution and growth of income. Human capital accumulation positively impacts on workers’ productivity in production and their bargaining power in wage negotiations. In the long-run equilibrium, a rise in the tax rate (which also denotes the share of output spent in human capital formation) lowers the pre- and after-tax wage share and physical capital utilization, and thus raises (lowers) the output growth rate when the latter is profit-led (wage-led). The impact of a higher tax rate on the employment rate (which also measures human capital utilization) in the long-run equilibrium is negative (ambiguous) when output growth is wage-led (profit-led). In any case, the supply of higher-skilled workers does not automatically create its own demand.

AbstractWe extend Becker’s model of discrimination by allowing firms to have discriminatory and favoring preferences simultaneously. We draw the two-preference parallel for the marginal firm, illustrate the implications for wage differentials, and consider the implied long-run equilibrium. In the short-run, wage differentials depend on relative preferences. However, in the long-run, market forces drive out discriminatory but not favoring firms.

Long Run Equilibrium

Gold and Indian culture have been sharing an age-old association. India is one of the top two consumers of gold. Gold is the most popular investment avenue because of its ability to provide liquidity. The average monthly price however has grown by 1,588 percent over the whole period from 1979 to 2017 (June). In this article, we intend to investigate gold as an investment to hedge against inflation. The sample period to study the relationship between gold and inflation is 2011–2017 (March). To analyze long-run equilibrium between gold and inflation (consumer price index [CPI]), Johansen’s cointegration approach has been used. The short- and long-run causality between gold and inflation has been studied using vector error correction model (VECM) and Wald test. The results of cointegration indicate that gold and CPI series are cointegrated and bear long-run equilibrium. Both VECM and Wald test results indicate that there is only long-run causality between CPI and gold prices. However, in short run these variables do not show any causality. Thus, we infer that gold investment can be used as hedge against Inflation. The findings of this research have got direct implications for retail investors, portfolio managers, treasury and fund managers, government, and commercial traders.

Long Run Equilibrium

This study investigates the long-run relationship between Ghana’s exports and imports for the period of 1948 to 2012. Using the Engle Granger two-step procedure we find that Ghana’s exports and imports are cointegrated. However, the slope coefficients from the cointegration equations were not statistically equal to 1. Furthermore, application of the error correction model reveals that 1% increase in the imports will significantly result in 0.56% increase in exports, suggesting that the exports’ responsiveness to imports is low. The estimated error correction coefficient suggests that 32% of the deviation from the long run equilibrium relation is eliminated, leaving 68% to persist into the next period. These results suggest persistence in the trade deficit and an option of curbing the deficit is to re-order the relationship between imports and exports with a view to reducing imports demand. These results imply that though Ghana’s past macroeconomic policies have been effective in bringing its imports and exports into a long run equilibrium, it is yet to satisfy the sufficient condition for sustainability of foreign deficit.

Long Run Equilibrium

Background The popularity of dengue can be inferred from Google Trends that summarizes Google searches of related topics. Both the disease and its Google Trends have a similar source of causation in the dengue virus, leading us to hypothesize that dengue incidence and Google Trends results have a long-run equilibrium. Objective This research aimed to investigate the properties of this long-run equilibrium in the hope of using the information derived from Google Trends for the early detection of upcoming dengue outbreaks. Methods This research used the cointegration method to assess a long-run equilibrium between dengue incidence and Google Trends results. The long-run equilibrium was characterized by their linear combination that generated a stationary process. The Dickey-Fuller test was adopted to check the stationarity of the processes. An error correction model (ECM) was then adopted to measure deviations from the long-run equilibrium to examine the short-term and long-term effects. The resulting models were used to determine the Granger causality between the two processes. Additional information about the two processes was obtained by examining the impulse response function and variance decomposition. Results The Dickey-Fuller test supported an implicit null hypothesis that the dengue incidence and Google Trends results are nonstationary processes (P=.01). A further test showed that the processes were cointegrated (P=.01), indicating that their particular linear combination is a stationary process. These results permitted us to construct ECMs. The model showed the direction of causality of the two processes, indicating that Google Trends results will Granger-cause dengue incidence (not in the reverse order). Conclusions Various hypothesis testing results in this research concluded that Google Trends results can be used as an initial indicator of upcoming dengue outbreaks.
