India’s.(RBI).first-order.condition.indicate.that.its.<br />

preferences. have. been. asymmetric. with. respect<br />

to. exchange-rate. management,. with. the. response.<br />

to. the. rate. <strong>of</strong>. rupee. appreciation. being. relatively.<br />

larger. than. to. the. rate. <strong>of</strong>. rupee. depreciation. <strong>of</strong>.<br />

the. same. magnitude.. This. behavior. is. shown.<br />

to. account. for. a. sizable. fraction. <strong>of</strong>. reserve.<br />

accretion. in. recent. years. by. V.. Mahambare,<br />

M.. Ramachandran. and. Naveen. Srinivasan. in.<br />

their. paper. titled. “Preference. asymmetry. and.<br />

international. reserve. accretion. in. India”. (Applied<br />

Economics Letters,. Vol.. 16,. Issue. 15,. October.<br />

<strong>2009</strong>,.pp..1543-46.).<br />

An. emerging. consensus. in. macroeconomics.<br />

suggests. that. the. New. Keynesian. Phillips. curve.<br />

(NKPC). augmented. by. a. backward-looking.<br />

‘persistent’. element. (dubbed. the. hybrid. NKPC).<br />

is. a. good. benchmark. model. usable. for. policy.<br />

evaluation.. The. addition. <strong>of</strong>. this. lag. term. is.<br />

designed. to. capture. the. inflation. persistence. that.<br />

is. left. unexplained. in. the. pure. forward-looking.<br />

model..Moreover,.this.specification.is.increasingly.<br />

being. promoted. as. providing. a. micro-founded.<br />

alternative. to. the. accelerationist. Phillips. curve,.<br />

with. estimated. coefficients. that. are. viewed.<br />

as. structural. parameters.. In. the. paper. “Is. the.<br />

Hybrid. New. Keynesian. Phillips. curve. immune.<br />

to. the. Lucas. Critique?,”. (Journal <strong>of</strong> Quantitative<br />

Economics,.New.Series.Vol..7.(2),.July.<strong>2009</strong>,.pp..<br />

96-105.). Naveen. Srinivasan. takes. issue. with. this.<br />

consensus. position.. Specifically,. he. shows. that.<br />

adding. this. inertial. element. makes. the. NKPC.<br />

vulnerable. to. the. Lucas. critique,. despite. the. fact.<br />

that. addressing. this. critique. is. a. major. focus. <strong>of</strong>.<br />

the.research.agenda.behind.this.approach.<br />

It. has. been. widely. argued. that. inflation<br />

persistence.since.WWII.has.been.widespread.and.<br />

durable. and. that. it. can. only. be. accounted. for. by.<br />

models. with. a. high. degree. <strong>of</strong>. nominal. rigidity..<br />

In. the. paper. “Can. the. facts. <strong>of</strong>. UK. inflation.<br />

persistence. be. explained. by. nominal. rigidity?”.<br />

(Economic Modelling,.Vol..26,.Issue.5,.September.<br />

<strong>2009</strong>,. pp.. 978-92),. David. Meenagh,. Patrick.<br />

Minford,. Eric. Nowell,. Prakriti. S<strong>of</strong>at. and. Naveen.<br />

Srinivasan.examine.UK.post-war.data.where.after.<br />

confirming. previous. studies’. findings. <strong>of</strong>. varying.<br />

persistence. due. to. changing. monetary. regimes,.<br />

find. that. models. with. little. nominal. rigidity. are.<br />

best.equipped.to.explain.it.<br />

In. “The. Structure. <strong>of</strong>. Inflation,. Information.<br />

and. Labor. Markets:. Implications. for. monetary.<br />

policy,”. (in. Pradeep. Agrawal,. Biswanath. Goldar<br />

and. Pulin. Nayak. (eds.). India’s Economy and<br />

Growth: Essays in Honor <strong>of</strong> V.K.R.V. Rao,. RP-<br />

<strong>2010</strong>-896). Ashima. Goyal. gives. a. simplified.<br />

version. <strong>of</strong>. a. typical. dynamic. stochastic. open.<br />

economy. general. equilibrium. models. used. to.<br />

analyze. optimal. monetary. policy.. The. paper.<br />

outlines. the. chief. modifications. when. dualism. in.<br />

labor. and. in. consumption. is. introduced. to. adapt.<br />

the. model. to. a. small. open. emerging. market.<br />

such. as. India.. The. implications. <strong>of</strong>. specific. labor.<br />

markets,. the. structure. <strong>of</strong>. Indian. inflation. and. its.<br />

measurement. are. examined.. Simulations. give.<br />

the. welfare. effects. <strong>of</strong>. different. types. <strong>of</strong>. inflation.<br />

targeting.. Flexible. CPI. inflation. targeting.<br />

(CIT). without. lags. works. best,. especially. if.<br />

the. economy. is. more. open.. But. volatile. terms.<br />

<strong>of</strong>. trade. make. the. supply. curve. even. steeper.<br />

than. in. a. small. open. economy. despite. specific.<br />

labor. markets. and. higher. labor. supply. elasticity..<br />

Exchange. rate. intervention. limits. the. volatility.<br />

<strong>of</strong>. the. terms. <strong>of</strong>. trade. and. improves. outcomes,.<br />

making. the. supply. curve. flatter.. As. long. as.<br />

such. intervention. is. required,. domestic. inflation.<br />
