This document summarizes a research paper on using fiscal rules and sovereign bond spreads to anchor fiscal policy expectations. It finds that a fiscal rule targeting a ceiling on sovereign bond spreads, or "spread brake", outperforms a rule targeting a ceiling on debt levels, or "debt brake". A spread brake provides a more robust policy anchor that is better suited for heterogeneous economies. It allows borrowing levels to vary appropriately with debt intolerance. A common spread brake threshold maximizes welfare gains compared to a common debt ceiling. Future work is needed to determine optimal spread thresholds and implementation of spread brakes.

Homework 51)a) the IS curve ln Yt= ln Y(t+1) – (1Ɵ)rtso th.docxadampcarr67227
Homework 5
1)
a) the IS curve: ln Yt= ln Y(t+1) – (1/Ɵ)rt
so the slope is: drt/dyt (is) = -Ɵ/Yt. That means that an increase in Ɵ will result in a steeper curve.
LM curve: Mt/Pt = Yt^(Ɵ/v) (1+rt / rt)^(1/v)
Ln(Mt/Pt) = (Ɵ/v) ln Yt +(1/v)ln(1+rt) – (1/v)ln rt.
0 = (Ɵ/v)(1/Yt)dYt + (1/v)(1/(1+rt)) drt – (1/v)(1/rt)drt.
The slope is: drt/dyt (LM) = (Ɵrt(1+rt))/Yt. That means that an increase in Ɵ will result in a steeper curve.
b) the curve IS is not affected by the value of V. while curve LM shifts upwards, since a decrease in v will result in an increase for the demand for real money.
c) IS is not affected byΓ(.)
optimal money holdings: BΓ’(Mt/Pt) = (it/(1+it)) U’(Ct)
B(Mt/Pt)^(-v) = (it/1+it) Yt^-Ɵ
Mt/Pt= B^(1/v) Yt^(Ɵ/v) (1+rt/rt)^(1/v)
So this means that the LM curve will shift downwards.
2)
a) AC= (PC/)+(αYP/2)i
AC/ = -(PC/^2) + (αYP/2)I = 0
C/^2 = αYi/2
So *=(2C/αYi)^(1/2)
b) average real money holdings:M/P= αY/2
M/P = (αY/2) (2C/αYi)^(1/2)
M/P= (αCY/2i)^(1/2)
Ln(m/p) = (1/2)(lnα+lnY+lnC-ln2-lni)
(1/(M/P))((M/P)/i) = -(1/2)(1/i)
Elasticity of real money with respect to i: ((M/P)/)(i/(M/P)) = -1/2
The elasticity with respect to Y : ((M/P)/Y)(Y/(M/P)) = ½
Average real money holdings increase in Y, and decrease in i.
4)
a)when p is at a level that generates maximum output, LS meets LD.
b) when p is above the level that generates maximum output, will cause unemployment.
7)
a)
b)i)
ii)
iii)
13)
a) the asset has an expected rate of return r. capital gain/loss plus dividends per unit time = rvp. There is no dividends per unit time while searching for the palm tree, and there is b probability per unit time of capital gain of (vc-vp)-c. the difference in the price of the asset is(vc-vp) and –c is what the asset pays, so at the end we have rvp=b(vc-vp-c)
b) there is probability aL that a person will find another person with a coconut and trade with that person and gain u̅. the difference in the price of the asset is (vp-vc). So we end up with
rvp=al(vp-vc+u̅).
c) vp=(rvc/aL)+vc-u̅.
r((rvc/aL )+vc-u̅)= b(vc-(rvc/aL)-vc+u̅-c)
vc(r(r+aL+b))/aL = u̅(r+b)-bc
the value of being in state C: vc= (aL(u̅(r+b)-bc)) / r(r+aL+b)
the value of being in state p: vp= ((u̅(r+b)-bc)/(r+aL+b)) + (aL(u̅(r+b)-bc)/r(r+aL+b)) - u̅
so finally
vc-vp = (bc+u̅aL)/(r+aL+b).
e) vc-vp ≥c
vc-vp = (bc+u̅a(b/a))/(r+a(b/a)+b) = (bc+bu̅)/(r+2b)
(bc+bu̅)/(r+2b) ≥ c
That means that
Bc+bu̅≥c and c(r+2b-b) ≤ bu̅
So finally we have
c≤ bu̅ / (r+b).
f) it is a steady-state equilibrium for no one who finds a tree to climb it for any value of c>0.
Yes there are values of c which there is more than one steady-state equilibrium for 0<c< bu̅/(r+b)
Yes, L = b/a has a higher welfare than L=0. When L=0 people don’t gain any utility since they don’t climb a tree and don’t have a chance to trade with other people and gain a coconut.

"Correlated Volatility Shocks" by Dr. Xiao Qiao, Researcher at SummerHaven In...Quantopian
Commonality in idiosyncratic volatility cannot be completely explained by time-varying volatility. After removing the effects of time-varying volatility, idiosyncratic volatility innovations are still positively correlated. This result suggests correlated volatility shocks contribute to the comovement in idiosyncratic volatility.
Motivated by this fact, we propose the Dynamic Factor Correlation (DFC) model, which fits the data well and captures the cross-sectional correlations in idiosyncratic volatility innovations. We decompose the common factor in idiosyncratic volatility (CIV) of Herskovic et al. (2016) into the volatility innovation factor (VIN) and time-varying volatility factor (TVV). Whereas VIN is associated with strong variation in average returns, TVV is only weakly priced in the cross section
A strategy that takes a long position in the portfolio with the lowest VIN and TVV betas, and a short position in the portfolio with the highest VIN and TVV betas earns average returns of 8.0% per year.
Summing up about growing and non growing perpetuities wacc levered and tax sa...Futurum2
In this note we reconsider in detail the proper discount rate for cash flows in perpetuity, the present value of tax savings and the calculation of terminal value. The note clarifies the use of real discount rates and concludes with a formulation that is inflation-neutral for a given assumption on the discount rate for the tax savings. We find that the only discount rate for tax savings that makes the value of the perpetuity inflation-neutral is Kd, the cost of debt. We also reconsider the intuitive approach to calculate the cost of capital for perpetuities from the nominal rates that compose that cost of capital, and then
converting it into real cost of capital using Fisher relationship.

when will pi network coin be available on crypto exchange.DOT TECH
There is no set date for when Pi coins will enter the market.
However, the developers are working hard to get them released as soon as possible.
Once they are available, users will be able to exchange other cryptocurrencies for Pi coins on designated exchanges.
But for now the only way to sell your pi coins is through verified pi vendor.
Here is the telegram contact of my personal pi vendor

how to sell pi coins at high rate quickly.DOT TECH
Where can I sell my pi coins at a high rate.
Pi is not launched yet on any exchange. But one can easily sell his or her pi coins to investors who want to hold pi till mainnet launch.
This means crypto whales want to hold pi. And you can get a good rate for selling pi to them. I will leave the telegram contact of my personal pi vendor below.
A vendor is someone who buys from a miner and resell it to a holder or crypto whale.
Here is the telegram contact of my vendor:

As of my last update, Pi is still in the testing phase and is not tradable on any exchanges.
However, Pi Network has announced plans to launch its Testnet and Mainnet in the future, which may include listing Pi on exchanges.
The current method for selling pi coins involves exchanging them with a pi vendor who purchases pi coins for investment reasons.
If you want to sell your pi coins, reach out to a pi vendor and sell them to anyone looking to sell pi coins from any country around the globe.
Below is the contact information for my personal pi vendor.
Telegram: @Pi_vendor_247
If you are looking for a pi coin investor. Then look no further because I have the right one he is a pi vendor (he buy and resell to whales in China). I met him on a crypto conference and ever since I and my friends have sold more than 10k pi coins to him And he bought all and still want more. I will drop his telegram handle below just send him a message.

how to sell pi coins in South Korea profitably.DOT TECH
Yes. You can sell your pi network coins in South Korea or any other country, by finding a verified pi merchant
What is a verified pi merchant?
Since pi network is not launched yet on any exchange, the only way you can sell pi coins is by selling to a verified pi merchant, and this is because pi network is not launched yet on any exchange and no pre-sale or ico offerings Is done on pi.
Since there is no pre-sale, the only way exchanges can get pi is by buying from miners. So a pi merchant facilitates these transactions by acting as a bridge for both transactions.
How can i find a pi vendor/merchant?
Well for those who haven't traded with a pi merchant or who don't already have one. I will leave the telegram id of my personal pi merchant who i trade pi with.

The European Unemployment Puzzle: implications from population agingGRAPE
We study the link between the evolving age structure of the working population and unemployment. We build a large new Keynesian OLG model with a realistic age structure, labor market frictions, sticky prices, and aggregate shocks. Once calibrated to the European economy, we quantify the extent to which demographic changes over the last three decades have contributed to the decline of the unemployment rate. Our findings yield important implications for the future evolution of unemployment given the anticipated further aging of the working population in Europe. We also quantify the implications for optimal monetary policy: lowering inflation volatility becomes less costly in terms of GDP and unemployment volatility, which hints that optimal monetary policy may be more hawkish in an aging society. Finally, our results also propose a partial reversal of the European-US unemployment puzzle due to the fact that the share of young workers is expected to remain robust in the US.
Falcon stands out as a top-tier P2P Invoice Discounting platform in India, bridging esteemed blue-chip companies and eager investors. Our goal is to transform the investment landscape in India by establishing a comprehensive destination for borrowers and investors with diverse profiles and needs, all while minimizing risk. What sets Falcon apart is the elimination of intermediaries such as commercial banks and depository institutions, allowing investors to enjoy higher yields.
US Economic Outlook - Being Decided - M Capital Group August 2021.pdfpchutichetpong
The U.S. economy is continuing its impressive recovery from the COVID-19 pandemic and not slowing down despite re-occurring bumps. The U.S. savings rate reached its highest ever recorded level at 34% in April 2020 and Americans seem ready to spend. The sectors that had been hurt the most by the pandemic specifically reduced consumer spending, like retail, leisure, hospitality, and travel, are now experiencing massive growth in revenue and job openings.
Could this growth lead to a “Roaring Twenties”? As quickly as the U.S. economy contracted, experiencing a 9.1% drop in economic output relative to the business cycle in Q2 2020, the largest in recorded history, it has rebounded beyond expectations. This surprising growth seems to be fueled by the U.S. government’s aggressive fiscal and monetary policies, and an increase in consumer spending as mobility restrictions are lifted. Unemployment rates between June 2020 and June 2021 decreased by 5.2%, while the demand for labor is increasing, coupled with increasing wages to incentivize Americans to rejoin the labor force. Schools and businesses are expected to fully reopen soon. In parallel, vaccination rates across the country and the world continue to rise, with full vaccination rates of 50% and 14.8% respectively.
However, it is not completely smooth sailing from here. According to M Capital Group, the main risks that threaten the continued growth of the U.S. economy are inflation, unsettled trade relations, and another wave of Covid-19 mutations that could shut down the world again. Have we learned from the past year of COVID-19 and adapted our economy accordingly?
“In order for the U.S. economy to continue growing, whether there is another wave or not, the U.S. needs to focus on diversifying supply chains, supporting business investment, and maintaining consumer spending,” says Grace Feeley, a research analyst at M Capital Group.
While the economic indicators are positive, the risks are coming closer to manifesting and threatening such growth. The new variants spreading throughout the world, Delta, Lambda, and Gamma, are vaccine-resistant and muddy the predictions made about the economy and health of the country. These variants bring back the feeling of uncertainty that has wreaked havoc not only on the stock market but the mindset of people around the world. MCG provides unique insight on how to mitigate these risks to possibly ensure a bright economic future.

3. MISSPECIFICATION, ANCHORS, AND “PRICES VS.
QUANTITIES”
...1 Policy recommendations that are robust to model
misspecification (Hansen and Sargent, 2008).
...2 Fiscal policy frameworks do not have an anchor that improves
commitment to future policies (unlike frameworks used for
monetary analysis; Leeper, 2010).
...3 Are prices or quantities the best planning instrument under
heterogeneity and uncertainty/risk (Weitzman, 1974; Poole, 1970,
for monetary policy)?

Blanchard (IMFdirect 2011): “Are old rules of thumb, such as
trying to keep the debt-to-GDP ratio below 60 percent in
advanced countries, still reliable?”
The Fiscal Monitor (2013): “The optimal-debt concept has
remained at a fairly abstract level... adjustment needs scenario
has used benchmark debt ratios of 60 percent of GDP... But the
appropriate debt target need not be the same for all countries...”
Eberhardt and Presbitero (JIE 2015): impossibility of finding
common debt thresholds across countries for the relationship
between debt levels and long-run growth.

9. THIS PAPER
Debt brake vs. spread brake: a debt (spread) brake imposes a
limit on the fiscal balance when the sovereign debt (spread) is
above a threshold.
The sovereign spread outperforms the debt level as the fiscal
anchor.
...1 More robust anchor/policy advice (Croatia? Portugal? Greece?
Spain? Peru? Brazil?).
...2 Better common anchor (EU).
...3 Could improve ownership/credibility/commitment.
Substantial gains from anchoring fiscal expectations.

11. ENVIRONMENT
Government’s income in period t = yt. With t ∈ {1, 2, 3}.
y1 = y2 = 0, y3 > 0 and stochastic with cdf F.
The government maximizes utility of a representative consumer
with discount factor β > 0.
A bond issued at t = 1 promises the payment sequence {δ, 1 − δ}.
A bond issued at t = 2 promises a payment of 1 at t = 3.
Foreign risk-neutral lenders’ discount factor = 1.
Lenders are atomistic and bond market is competitive.
Cost of defaulting: Lose fraction ϕ of y3 (no default in first two
periods)
11 / 112
12. OPTIMAL POLICIES
Ramsey borrowing: sequence of borrowing that maximizes the
government’s expected utility in period 1, given the default rule
of the period 3 government.
Markov borrowing: sequence of borrowing chosen sequentially
by the governments in periods 1 and 2.

13. TIME INCONSISTENCY (DEBT DILUTION)
.
Proposition
..
......
Suppose δ < 1; i.e., the government issues long-term debt in period 1.
Then, Markov policies and Ramsey policies do not coincide.
13 / 112
15. (NO MODEL UNCERTAINTY OR HETEROGENEITY)
PRICES = QUANTITIES
Idiosyncratic debt brake imposes a ceiling on the debt level,
(1 − δ)b1 + b2 ≤ ¯b.
Idiosyncratic spread brake imposes a ceiling on the spread paid
by the government and thus a floor on the sovereign bond price,
q2(b1, b2) ≥ q.
.
Proposition
..
......
If the government’s choices in period 2 are limited with either a debt
brake with threshold ¯b∗ = (1 − δ)bR
1 + bR
2 or a spread brake with
threshold q∗ = q2(bR
1 , bR
2 ), Markov policies coincide with Ramsey
policies. 15 / 112

Proposition

Suppose u(c) = c, δ = 0,
ζq(b) =
b
ϕ
f
(
b
ϕ
)
1 − F
(
b

)
is increasing with respect to b, and limb→∞ ζq(b) ≥ 1. Consider any set
of economies that are different only in the value of the cost of
defaulting ϕ. Then, Ramsey policies are given by {bR
1 = ηϕ, bR
2 = 0},
where η ∈ R++ satisfies
1 − η
f (η)
1 − F (η)
= β2
.
16 / 112
17. CONSTRAINED RAMSEY
...1 Robust rule under risk/uncertainty: planner needs to chose a
idiosyncratic non-contingent rule for one economy, before
knowing value of ϕ.
...2 Common rule under heterogeneity: planner needs to choose the
same rule for every economy in a set of economies that are
different only in the value of the cost of defaulting ϕ.
17 / 112
18. COMMON SPREAD BRAKE ≻ COMMON DEBT BRAKE
Note that q2(b1, b2) = 1 − F
(
b1(1−δ)+b2
ϕ
)
and {bR
1 = ηϕ, bR
2 = 0}.
Therefore, the price limit consistent with Ramsey borrowing does not
depend on ϕ.
.
Proposition
..
......
Suppose u(c) = c, δ = 0, ζq(b) is increasing with respect to b, and
limb→∞ ζq(b) ≥ 1. Consider any set of economies that are different
only in the value of the cost of defaulting ϕ. The optimal common
spread-brake threshold for any such set is Q∗
= 1 − F(η) and achieves
the Ramsey allocation in every economy of the set. Furthermore, Q∗
generates larger welfare gains than any common debt brake ¯B.

20. THE MODEL
Because of long-term debt, expectations about future debt levels
determine the endogenous sovereign spread.

35. CONCLUSIONS
Maybe sovereign spreads should play a more prominent role in
anchoring discussions of fiscal policy
Economies that suffer less debt intolerance should be allowed to
issue more debt.
It may be much easier to enforce a spread brake than to enforce a
debt brake.
Also
a market-determined fiscal anchor could be less susceptible to
creative accounting
more comprehensive measure of fiscal risks (e.g., debt maturity,
currency composition, implicit or contingent liabilities) 35 / 112
36. NEED FOR FUTURE WORK?
What should the spread-brake threshold be? Should it be reduced
gradually (mimicking disinflation periods)?
Which interest rates should fiscal rules use?
The average spread over which period should be used to trigger
the spread brake?
How should a spread brake be complemented with other
numerical targets?
How fast should the fiscal adjustment triggered by the brake be?
Would the spread limit help with other shocks (bailout
probability, multiple equilibria, political shocks, debt shocks)?
36 / 112
39. EQUILIBRIUM CONCEPT
...1
Markov Perfect Equilibrium.
Each period the government decides taking as given bond prices
and future defaulting, spending, taxing, and borrowing strategies.
Current optimal choices are consistent with future government
strategies.
Limit of finite-horizon economy.
39 / 112
42. IF THE GOVERNMENT PAYS ITS DEBT OBLIGATIONS
Issues long-term debt.
Bonds are perpetuities with geometrically decreasing coupon
obligations
Important for the quantitative performance of the model
(Hatchondo and Martinez 2009; Chatterjee and Eyigungor 2012).
Chooses provision of public good: g
Chooses labor tax: τ
42 / 112
43. IF THE GOVERNMENT DEFAULTS
Chooses g and labor tax τ while in default.
Two costs of defaulting:
...1 Exclusion from credit market for a stochastic number of periods.
...2 Fall in TFP in every period in which the government is in default.
With constant probability, the government can exit the default by
exchanging α new bonds per bond in default (debt restructuring).
1 − α = haircut

Proposition

Suppose δ = 1; i.e., bonds issued in period 1 pay off in period 2 alone.
Then, the government’s expected utility in period 1 cannot be
improved with a fiscal rule that limits debt choices in period 2.
The period-2 government chooses the borrowing level b∗

maximizes the government’s expected utility in period 1.

Automatic budget corrections when the spread-brake threshold

Independent fiscal councils
Focusing on the more transparent benefits from lower interest
rates instead of on the more controversial effects of lower debt
levels may improve a country’s ownership of the its fiscal rule.
Conceptually, it may be easier to commit to a spread brake than to
an inflation target.

A “common spread-brake” fiscal rule mitigates the deficit bias in

A “common debt-brake” fiscal rule does not.

as a common and robust fiscal anchor.

112. OPTIMAL “COMMON AND ROBUST” FISCAL
ANCHOR
Consider a set of heterogenous economies indexed by the value of
the parameter θ ∈ {ϕ, σy, β}.
v(x; θ) = period 1 expected utility in an economy with a Ramsey
planner that chooses instrument x.
h(θ) = density function for θ in the set.
