Reforming IndiaĂ¹ùâÂŹĂąâÂąs Fiscal Transfer System : Resolving Vertical and Horizontal Imbalances
Two central problems in a fiscal transfer systemrelate to resolving vertical and horizontal imbalances. In the context of the setting of the 13th Finance Commission, this paper looks at the methodological background of fiscal transfers followed by recent Finance Commissions in India, particularly the Twelfth Finance Commission (TFC). It is noted that in India, there is long - term stability in the share of states after transfers in the combined revenues of the centre and the states. It is argued that this stability depends on linking the share of states in the transfers, particularly tax devolution with the difference in the buoyancies of central and states taxes. In the context of horizontal imbalance, it is argued that some of the recent Finance Commissions have implicitly followed an axiomatic approach to tax devolution and brought in some normative elements in determining grants. In spite of large difference in fiscal capacities, a high degree of equalization has been achieved. It is shown, for example, that in the case of TFC recommended transfers, nearly 88 percent of needed equalization was achieved while devoting 50 percent of transfers to resolving vertical imbalance. Amethodology is also developed to determine weights of vertical and equalizing components of transfers through devolution. In the case of the Twelfth Finance Commission, the horizontal component of tax devolution is strengthened by a scheme of equalizing health and education grants.fiscal transfer system, vertical imbalance, horizontal imbalance, Twelfth Finance Commission
Pay Me Later: Inside Debt and Its Role in Managerial Compensation
Inside debt, such as pensions and deferred compensation, constitutes a widely-used form of executive compensation, yet the valuation and incentive effects of these instruments have been almost entirely overlooked by prior work. Our paper initiates this line of research by studying CEO pension arrangements in a sample of 237 large capitalization firms. Among our findings are that CEO compensation in most large cap firms exhibits a balance between debt- and equity-based incentives, with the balance shifting systematically away from equity and toward debt as CEOs growolder; that annual increases in pension entitlements represent about 10% of overall compensation for the CEOs in our sample, and about 15% for CEOs aged 61 to 65; that CEOs with high debt-based incentives manage their firms conservatively to reduce default risk; and that pension plan compensation strongly influences patterns of CEO turnover and CEO cash compensation.CEO pensions; inside debt; deferred compensation
On the Weakening of Chromospheric Magnetic Field in Active Regions
Simultaneous measurement of line-of-sight (LOS) magnetic and velocity fields
at the photosphere and chromosphere are presented. Fe I line at
and at are used respectively for deriving the
physical parameters at photospheric and chromospheric heights. The LOS magnetic
field obtained through the center-of-gravity method show a linear relation
between photospheric and chromospheric field for field strengths less than 700
G. But in strong field regions, the LOS magnetic field values derived from
are much weaker than what one gets from the linear relationship
and also from those expected from the extrapolation of the photospheric
magnetic field. We discuss in detail the properties of magnetic field observed
in from the point of view of observed velocity gradients. The
bisector analysis of Stokes profiles show larger velocity
gradients in those places where strong photospheric magnetic fields are
observed. These observations may support the view that the stronger fields
diverge faster with height compared to weaker fields.Comment: accepted for publication in Ap
Textpresso for Neuroscience: Searching the Full Text of Thousands of Neuroscience Research Papers
Textpresso is a text-mining system for scientific literature. Its two major features are access to the full text of research papers and the development and use of categories of biological concepts as well as categories that describe or relate objects. A search engine enables the user to search for one or a combination of these categories and/or keywords within an entire literature. Here we describe Textpresso for
Neuroscience, part of the core Neuroscience Information Framework
(NIF). The Textpresso site currently consists of 67,500 full text
papers and 131,300 abstracts. We show that using categories in
literature can make a pure keyword query more refined and meaningful.
We also show how semantic queries can be formulated with categories
only. We explain the build and content of the database and describe the
main features of the web pages and the advanced search options. We also
give detailed illustrations of the web service developed to provide
programmatic access to Textpresso. This web service is used by the NIF
interface to access Textpresso. The standalone website of Textpresso
for Neuroscience can be accessed at

CDS Credit-Event Auctions
Credit-event auctions were introduced in 2005 to facilitate cash
settlement in the credit default swap market following a credit event.
They have a novel two-stage structure that makes them distinct from
other auction forms. This paper studies outcomes in credit-event
auctions over the period 2008-10. Our analysis is in three parts. In the
rst part, we look at the ecacy of price discovery in the auction. We nd
that the auction price has a signicant bias relative to the pre- and
post-auction market prices for the same instruments, and that volatility
of market prices often increases after the auction; nonetheless, we find
that information generated in the auction is very valuable for
post-auction market price formation. In the second part of the analysis,
we look at behavior within and across auctions and the factors that in
uence it. We find, among other things, that \winner's curse"
concerns play a central role, affecting liquidity provision in the
auction, the pricing bias, and bidders' within-auction updating of their
private information. In the nal part of the paper, under some
simplifying assumptions, we carry out a structural estimation to recover
the underlying distribution of signals. Using these estimates, we find
that the alternative auction formats could reduce the amount of bias in
the auction final price
Denumerable-Armed Bandits
This paper studies the class of denumerable-armed (i.e. finite- or countably infinitearmed)
bandit problems with independent arms and geometric discounting over an
infinite horizon, in which each arm generates rewards according to one of a finite number
of distributions, or "types." The number of types in the support of an arm, as also the
types themselves, are allowed to vary across the arms. We derive certain continuity and
curvature properties of the dynamic allocation (or Gittins) index of Gittins and Jones
(1974), and provide necessary and sufficient conditions under which the Gittins-Jones
result identifying all optimal strategies for finite-armed bandits may be extended to
infinite-armed bandits. We then establish our central result: at each point in time, the
arm selected by an optimal strategy will, with strictly positive probability, remain an
optimal selection forever. More specifically, for every such arm, there exists (at least) one
type of that arm such that, when conditioned on that type being the arm's "true" type,
the arm will survive forever and continuously with nonzero probability. When the reward
distributions of an arm satisfy the monotone likelihood ratio property (MLRP), the
survival prospects of an arm improve when conditioned on types generating higher
expected rewards; however, we show how this need not be the case in the absence of
MLRP. Implications of these results are derived for the theories of job search and
matching, as well as other applications of the bandit paradigm
