This paper discusses on-time performance (OTP) for long-distance passenger trains operating over tracks that are owned and operated by freight railroads. OTP is addressed primarily from the point of view of the host railroad. A brief literature review identifies practices that are commonly used by railroads and other modes to develop and implement achievable schedules. Analysis of travel time, train delay and other data for Amtrak trains operating on CSXT's I95 Corridor documents actual levels of reliability and the primary causes of poor OTP. Comparison of performance for passenger trains and various classes of freight trains demonstrates that Amtrak trains operate much faster and more reliably than CSXT's trains. Potential means of improving the OTP of Amtrak trains are discussed. While providing high quality track with sufficient capacity is the long-run solution for upgrading OTP, a short-run solution is to base schedules on past performance ("experience-based scheduling"). After Amtrak increased the schedule of the Auto Train by one hour in 2006, OTP improved from less than 10% in early 2006 to 82% for the first half of 2008. Analysis of the travel time distributions of the other long-distance Amtrak trains operating on CSXT's I95 Corridor from 2004 to 2008 indicates that a similar schedule increase would also have brought these other trains close to Amtrak's goal of 80% OTP. Schedules that reflect track maintenance requirements and other known seasonal and weekly factors would allow further improvements in measured OTP. Additional measures of performance concerning the probability and extent of late arrivals would be beneficial to travelers in planning their trips.

AbstractIntegrated economic models have become popular for assessing climate change. In this paper we show how these methods can be used to assess the impact of a discard ban in a fishery. We state that a discard ban can be understood as a confiscatory tax equivalent to a value-added tax. Under this framework, we show that a discard ban improves the sustainability of the fishery in the short run and increases economic welfare in the long run. In particular, we show that consumption, capital and wages show an initial decrease just after the implementation of the discard ban then recover after some periods to reach their steady-sate values, which are 16–20% higher than the initial values, depending on the valuation of the landed discards. The discard ban also improves biological variables, increasing landings by 14% and reducing discards by 29% on the initial figures. These patterns highlight the two channels through which discard bans affect a fishery: the tax channel, which shows that the confiscation of landed discards reduces the incentive to invest in the fishery; and the productivity channel, which increases the abundance of the stock. Thus, during the first few years after the implementation of a discard ban, the negative effect from the tax channel dominates the positive effect from the productivity channel, because the stock needs time to recover. Once stock abundance improves, the productivity channel dominates the tax channel and the economic variables rise above their initial levels. Our results also show that a landed discards valorisation policy is optimal from the social welfare point of view provided that incentives to increase discards are not created.

Purpose Among the many factors fueling the inflationary tendencies in an economy such as monetary shocks, structural shocks, demand shocks, external shocks and demographic changes, the issue of inflation (INF) has also been found to be related to fiscal policy decisions of the government. The purpose of this study is to investigate the inflationary tendencies in India particularly from the fiscal point of view. The study also examines the influence of other potential determinants such as output growth rate, interest rate, trade-openness (TO) and oil price inflation (OPI). Design/methodology/approach To examine the dynamic nature of association between fiscal deficit and inflation, the study applies the Toda-Yamamoto (1995) test and Breitung and Candelon (2006) test to investigate the nature of causality in time and frequency domain frameworks. In addition, to scrutinize the possibility of a long-run association, that too from an asymmetric point of view, the study applies a Non-linear Autoregressive Distributed lag model (NARDL) given by Shin et al. (2014). Finally, non-linear cumulative dynamic multipliers are used to trace the traverse between disequilibrium position of short-run and subsequent long-run equilibrium of the system. Findings The authors found a unidirectional causality from fiscal deficit to inflation in case of time domain analysis and no feedback causality is reported. However, in case of frequency domain design, causality from fiscal deficit to inflation is found at low frequencies only, i.e. no short-run causality is established and hence dynamic nature of the relationship between the two variables is vindicated. Using NARDL model, the results document the existence of an asymmetric long-run direct association between fiscal deficit and inflation. However, an increase in deficit is found to be more inflationary and a decrease affects the inflation with a lower magnitude. The asymmetric impact of fiscal deficit on inflation can be explained through the existence of liquidity constraints, consumption-investment downward inflexibility and the downward price stickiness. Contractionary monetary policy action is found to be more effective than an expansionary one, signifying the asymmetric influence of monetary policy actions on the inflation of India. Similarly, in a supply-constrained economy with downward price rigidity, the authors found an asymmetric impact of output growth and output decline on inflation. As regard to the trade-openness, although an asymmetry is reported, the signs refute the validation of Romer (1993) hypothesis. Finally, the impact of oil price inflation on the inflationary pressures is according to theory but the coefficients are devoid of statistical significance. Practical implications These results indicate some important policy recommendations. Fiscal consolidation strategy should be executed in an appreciable manner to achieve the sound fiscal health and lower INF. The disciplined fiscal strategy would also be imperative for an effective monetary policy. Monetary authorities should possess noticeable credibility to manage the macroeconomic system and policy stances should be implemented according to requirements of the economy. Growth in output should be encouraged to have two-fold benefits to the economy – reducing INF on the one hand and fiscal deficits on the other. Originality/value The study contributes to the existing literature in the following ways. First, taking note of dynamic nature of the relationship between these two variables, the study examined the deficit INF nexus in a dynamic and asymmetric framework. The novelty of the study is ensured by the very nature of it is the first study in case of India to identify the fiscal INF in an asymmetric configuration. The authors applied a NARDL model, given by Shin et al. (2014) to examine the existence of any cointegrating relationship in an asymmetric paradigm. Second, the nature of causality between fiscal deficit and INF has been examined in a time domain and FD framework to portray precisely the casual interactions between these two variables in the short-run and long run. The study will, therefore, enrich the existing literature along the asymmetric lines.

This study explores the asymmetric effect of exchange rate volatility on tourism demand in India from January 2006 to April 2018. Tourism demand is captured from a twin perspective—quantity and value. While quantity is represented by foreign tourist arrival in India, earnings from foreign tourists are used to represent value. The study is unique from a methodological point of view as it makes the first ever application of the nonlinear autoregressive distributed lag model of Shin, Yu, and Greenwood-Nimmo (2014), in the tourism demand literature to capture nonlinearity simultaneously in the short- as well as long-run. Results of our analysis show that tourism demand in India responds asymmetrically to both nominal and real exchange rate volatility. Also, the long-run effects of exchange rate uncertainty are shown to be more damaging than the short-run effects. Our findings are fairly robust to alternative specifications.

The fertiliser industry in developing countries is facing challenge and uncertain future due to their commitments to the WTO. This is part of the reason that the developing countries are pushing for reducing of subsidies given by the developed countries to their agriculture which is much bigger making the subsidies to agriculture becoming a contentious issue in the WTO negotiations. Some of the subsidies are accepted in the WTO context whereas the others are not. In India the farm sector subsidies are given in the form of irrigation, electricity, fertilisers etc. By far the fertiliser and food subsidies are the most significant amounting to about US$9.3 billion in 2004 (less than 0.5 percent of GDP). Thus, while from the WTO point of view, it is not necessary to reduce fertiliser subsidy in India. However, because of the WTO commitments, quantitative restrictions in this sector had to be removed by the end of March 2001 in India. Cheaper imports have been threatening the domestic industry specially the units that do not use gas as feedstock. In the short run domestic companies may enjoy the protection of differential subsidy in some form or the other. But in the long run they will have to compete on a stand-alone basis. This paper examines the experience and impact of fertiliser subsidy across various countries and shows that it is a common tool to promote farm production. But the evidence shows that the fertiliser subsidy tends to benefit the rich farmers more than the poor farmers. The study examines the different approaches used by the policymakers to reach the targeted farmers. In this context the paper records the evidence from some countries where the fertiliser industry has come forward and complemented the policymakers' efforts to meet this objective and in the process ensured their better future.

The causal relationship between poverty, education and economic growth has been widely studied in many countries, however, the results of a lot of studies demonstrate a controversial point of view and diverse conclusions which may be caused by differences in methodologies and development policies. The purpose of this study is firstly, to investigate the dynamic causality relationship between education, poverty, and economic growth both in the short and long-run, secondly, to analyze the dynamic response of poverty to shocks of education and economic growth. This study applied the quantitative method approach by using Panel Error Error Correction Model (PVECM). All secondary data was taken from BPS, in the form of panel data of 33 provinces in Indonesia during the period 2010-2018. This study found strong evidence that there was a long-run feedback causality linkage between poverty, education, and economic growth, while in the short-run, only found a bi-directional causality relationship between education and economic growth. The shocks of education and economic growth were responded negatively by the poverty variable, indicating that improving the quality of education and economic growth plays a vital role or has an impact on poverty reduction.

The relationship between revenue and government expenditure is an important subject in public economics especially for Iran country, which is suffering from persistent budget deficits. From point of view of theoretical studies, there are essentially four schools of thought on the direction of causation between government expenditure and revenue. The main purpose of this study is to investigate the Long and short Run relationship between government revenue and government expenditure in Iran Country covering data 1978- 2012 with using An Auto Regressive Distributive Lag (ARDL) Approach. The Iranian economy has been subject to a multitude of structural changes and regime shifts during the sample period. First, time series properties of the data are first analysed by Augmented Dickey-Fuller (ADF), Zivot-Andrews and Lee – Strazicich (2003, 2004) model. The results of the ADF and Lee – Strazicich models indicate that all series under investigation are non-stationary at level. However, it is evident from the results of Augmented Dickey-Fuller and Lee – Strazicich tests that revenue and government expenditure are stationary at first difference because null hypotheses of unit roots for all the variables are rejected at 1 percent significance level then, we investigated causality between revenue and government expenditure by using an application of Toda-Yamamoto approach. Their evidence generally found unidirectional causality running from government revenue to government expenditure. So, these results consistent with the revenue-spend hypothesis. In the three stage, Autoregressive Distributeded Lag (ARDL) technique is used to describe both long run relationships and short run dynamic adjustments between government revenue and expenditure variables. The results of this paper support the Freidman (1978) hypothesis that government revenues cause expenditure and revenues have a positive causal impact on government expenditure.

Current economical trends create new requirements to population mobility. People always travel for many reasons and they are very dependent on the system of passenger transport. There are several modes of transport, but passengers mostly use road and rail transport. Passenger transport system is influenced by many qualitative factors with various impacts. Long-distance passenger trains have got significant position on the transport market, what represents demand and offer in the passenger transport system. These trains connects far places therefore transport accessibility in the region or country is better and passenger railway transport is more attractive for traveling public. This article is focused on main purpose of these trains from operational and economical point of view.

Purpose: Since 1990s, the discussion on whether mutual funds can perform better and persistently as compare to market has become an ongoing issue. Current research investigates the performance persistence of equity mutual funds’, particularly in the financial market of Bangladesh.Theoretical Framework: Different researchers have strived to examine the performance of mutual funds by using numerous performance indicators and risk adjustment techniques.Design/Methodology/Approach: The equity mutual funds data for this study are obtained from DSE (Dhaka Stock Exchange) database. The sample set includes all open-end mutual funds from 2010 to 2015. There is no mutual fund that has ceased trade or merged with other mutual funds during the study period.Originality/Value: Broad literature have been directed on the performance and persistence of mutual funds in the American markets, while some of the studies also centered on Australia, China, Hong Kong and U.K. financial markets. However, in the context of Bangladesh’s financial market, no identical research has been carried on the performance persistence of mutual funds.Findings: The results reveal that the managers of equity mutual funds have selective ability to obtain higher returns in Bangladesh. Moreover, the past performance of mutual funds has an impact on their future performance. The size of mutual funds doesn’t have any impact on their performance. The parametric and non-parametric models demonstrate that as compare to long run, equity mutual funds in Bangladesh could perform persistently in the short-run.

The study was conducted in Rajshai Barind area to know the short and long term impact of for cylinder manual (Pedal) Pump developed by Bangladesh Agricultural Research Institute. The Pump was dominated by small farmers who cultivated vegetables in homestead fallow land. Simple cost and return analysis indicated that the pump was profitable in the short-run. It was found that in both private and social point of view the pump was profitable and acceptable in the short run as well as in the long run. The command area of the pump was 0.20 ha. The pump was found underutilized. For full utilization of the pump, its operation should be extended to the main field where water source is available. Nevertheless, the pump is a substitute to modern irrigation system. Key words: Pedal pump, irrigation, vegetable production.

In this document, we analyse the strategic complementarity between technological investment and investment in training by workers. We show that, beyond the importance of the answer to the question about which factor determines which, initial minimal conditions in both factors are required to start a long-run social development process. If these minimums are not met, the economy can become a self-satisfied economy, with a social mediocre performance but, at least in the short run, successful from the individual point of view. We consider that either manager of firms as workers are rational agents who make decisions about their future behaviour, considering the current state of the economy, understanding for such, the percentage of innovative and non-innovative firms in the market and the percentage of skilled and unskilled workers in the labour market. While managers decide the best way to invest, workers decide whether to invest or not in the upgrade or in the development of their skills to face the new challenges posed by technological change. The evolution of the economy is summarized in a complex dynamical system represented by a coupled dynamical system very close to the replicator dynamics considered in evolutionary game theory. In this way, we show that the initial conditions play a crucial role to understand the possibilities of future performance of the economy in each country, and, on the other hand, we analyse the conditions that make possible or necessary the intervention of the government in the economy.
