Real time location prediction with taxi-GPS data streams

Arnab Kumar Laha and Sayan Putatunda

Transporation Research Part C: Emerging Technologies

The prediction of the destination location at the time of pickup is an important problem with potential for substantial impact on the efficiency of a GPS enabled taxi service. While this problem has been explored earlier in the batch data set-up, we propose in this paper new solutions in the streaming data set-up. We examine four incremental learning methods using a Damped window model namely, Multivariate multiple regression, spherical-spherical regression, Randomized spherical K-NN regression and an Ensemble of these methods for their effectiveness in solving the destination prediction problem. The performance of these methods on several large datasets are evaluated using suitably chosen metrics and they were also compared with some other existing methods. The Multivariate multiple regression method and the Ensemble of the three methods are found to be the two best performers. The next pickup location problem is also considered and the aforementioned methods are examined for their suitability using real world datasets. As in the case of destination prediction problem, here also we find that the Multivariate multiple regression method and the Ensemble of the three methods gives better performance than the rest.

Farmer producer organizations as farmer collectives: A case study from India

Nalini Bikkina, Rama Mohana R. Turaga, and Vaibhav Bhamoriya

Development Policy Review

Small and marginal farmers in India have been vulnerable to risks in agricultural production. Several organizational prototypes are emerging to integrate them into the value chain with the objectives of enhancing incomes and reduction in transaction costs. One such alternative is Farmer Producer Organizations (FPOs). We explore the potential of FPOs as collective institutions through a case study of Avirat, one of the first FPOs in Gujarat. Our analysis suggests that FPOs have the potential to provide benefits through effective collective action. The main challenge, however, is to raise sufficient capital that can maximize these benefits. We discuss the implications of our findings to policy

Dispersion in macroeconomic volatility between the core and periphery of the international trade network

Anindya S. Chakrabarti

Journal of Economic Dynamics and Control

At the country level, macroeconomic volatility tends to correlate with trade openness although the direction of correlation is not stable across samples. Here I consider trade networks as sum of all pairwise trade linkages to emphasize that different linkages contribute differently to the transmission or mitigation of shocks, and show that across the network volatility is inversely related to centrality, a summary measure of strength of the linkages specific to a country. I study a multi-country, multi-sector trade model
subject to idiosyncratic productivity and liquidity shocks, and characterize volatility as an explicit function of centrality, diversification and the Herfindahl of the trade network in equilibrium. With sufficient skewness in trade linkages across countries, similar shocks generate different levels of repercussions across the network. The conventional effect of diversification holds true that countries with better diversified portfolio fluctuate less compared. Centrality directly contributes to better aggregation of shocks. Combined effect of these two channels dominates the opposite effect that a more central country is also more exposed to shocks. The model calibrated to the E.U. generates and closely replicates the negative relationship between centrality and volatility. The
theoretical model is then extended to capture stochasticity and sparsity in the trade networks.

Earnings management strategies during financial distress

Neerav Nagar and Kaustav Sen

IUP Journal of Accounting Research & Audit Practices

We examine whether financial distress and its severity have a role to play in managers' decisions with respect to the choice of earnings management strategies. Our results suggests that firms in initial stages of distress engage in real earnings management through a reduction in the spending on selling, general and administrative expenses, and engage in classification shifting to increase profitability and liquidity. When distress becomes severe, firms cut-back on production, engage in income-increasing accruals management, and increase their spending on selling, general and administrative expenses. Initial under-spending on selling, general and administrative expenses is opportunistic with an intention to show improved performance. In extreme distress, increase on such spending is a sound economic decision. Our findings provide insights into how managers of distressed firms trade-off between liquidity, profitability and solvency in both short-run and long-run.

Lighting up Lives through Cooking Gas and transforming society

S. K. Barua and Sobhesh Kumar Agarwalla

The study, reported in the form of a case, narrates the story of a major attempt at social transformation through a simple mechanism of providing cooking gas (LPG) to the marginalized in society. Targeting about 100 million households in India who still use dung-cakes, firewood, and coal as the primary fuel for cooking, the Pradhan Mantri Ujjwala Yojana (PMUY) was conceived with the objective of replacing these traditional fuels with LPG which is a clean fuel. The initial target of providing 50 million Below Poverty Line (BPL) families with LPG at the time of the launch of the scheme on May 1, 2016 was increased to 80 million by 2019-20, and as of January, 2018 over 30 million families had already been covered by the scheme.

The key findings are as follows. The scale and speed of implementation were achieved through excellent coordination between the government system, the government-owned Oil Marketing Companies (OMCs) and the banking system. The government system represented by officials from the central government, the state governments, and the village heads (Sarpanchs) helped in identifying BPL beneficiaries and in mobilizing people to canvass the idea of switching over to LPG from traditional fuels for cooking. The OMCs (the three companies involved in the implementation were IOCL, BPCL and HPCL) designed and created the robust logistics system needed for bottling and distribution of cooking gas. They also designed and created the IT platform required for easy transaction and record keeping for the entire logistics system. The banks provided the infrastructure needed for flow of funds, including flow and accounting of subsidies from the government.

PMUY is clearly one of the largest social intervention schemes executed anywhere in the world in challenging environment. Its successful implementation provides insights into management of such interventions. The lessons that can be drawn from the implementation would be of use for similar large-scale social interventions.

Too much care? Private health care sector and surgical interventions during childbirth in India

Mitul Surana and Ambrish Dongre

This paper evaluates the role of the private sector in performing one of the common surgical interventions, i.e. caesarean sections during childbirth in India. We use the latest round of National Family Health Survey to estimate the differential probability of C-section in private medical facilities relative to government facilities. We employ two estimation techniques, Household Fixed Effects and Coarsened Exact Matching, to reduce the extent of selection bias in the choice of delivery location. We also take advantage of a new question introduced in the survey which allows identification of planned C-sections which are more likely to be the result of either demand for C-section or unobservable (in the data) medical risks. We find that the probability of an unplanned C-section is 13.5-14 percentage points higher in the private sector. Given that some of the planned C-sections could be a result of supplier-induced demand, this is a very conservative estimate. Our results suggest that there were potentially 0.9 million preventable C-sections in the private sector in 2016. These results therefore call for a critical assessment of the role of private sector in healthcare in the context of inadequate public provision, expanding private provision and weak governance structures.
