assistant<br />

LETTER FROM THE<br />
CHAIR<br />
Greetings to all 'Canes near and far!<br />
year and report on some of our main achievements.<br />
excited to have them as colleagues!<br />
acknowledge them here. Thank you all!
In addition to research and teaching, the Economics Department is<br />
committed to serving the community by hosting public events<br />
featuring prominent policy makers and academics discussing<br />
important policy issues. We held two major events this spring.<br />
On February 2, <strong>2024</strong>, we hosted a conference entitled “Argentina<br />
in Transition.” This event brought several leading Latin American<br />
academics to discuss President Javier Milei’s radical proposals to<br />
combat Argentina’s raging inflation. The conference was the<br />
brainchild of Allan Herbert who co-organized the event with<br />
Manuel Santos and Alex Horenstein.<br />
On April 2, <strong>2024</strong>, we hosted the annual Henry Family Endowed<br />
Speakers Series featuring James Bullard, former president and<br />
CEO of the Federal Reserve Bank of St. Louis and current Dean of<br />
the Mitchell E. Daniels, Jr. Business School at Purdue University,<br />
whose public lecture was entitled “Can the Fed Stick the Soft<br />
Landing?” You can learn about these events and more on the<br />
pages that follow. Let us know if you have anything you’d like to<br />
share with our community in our future newsletters. Also, please<br />
feel free to reach out if you or your organization need speakers for<br />
your events, or if you’d just like to learn more about our plans. We<br />
have several exciting ideas on the table and we’re looking for<br />
partners.

Welcome to our department!<br />
Introducing our New Faculty<br />
Chad Kendall<br />
Chad Kendall is an applied microeconomist<br />
who specializes in political economy and<br />
behavioral economics. He is particularly<br />
interested in financial markets and voting<br />
mechanisms, and in the roles that<br />
information and bounded rationality play in<br />
the functioning of these institutions. His<br />
work has been published in top leading<br />
journals including Econometrica and the<br />
American Economic Review.<br />
Henrique Castro Pires<br />
Henrique Castro-Pires received his Ph.D. in<br />
Managerial Economics and Strategy from the<br />
Kellogg School of Management, Northwestern<br />
University, in 2022. Upon graduation, he worked<br />
as an Assistant Professor of Economics at the<br />
University of Surrey for two years. His research<br />
interests lie in the field of microeconomic theory,<br />
including mechanism design, organizational<br />
economics, and personnel economics. His recent<br />
research has focused on the design of incentive<br />
schemes, subjective performance evaluations,<br />
and how compensation schemes affect the<br />
selection of workers who join a given firm or<br />
organization. His work has been published in top<br />
journals in the field, including the American<br />
Economic Review, the Journal of the European<br />
Economic Association, and the Games and<br />

“CAN THE FED STICK THE SOFT LANDING?”<br />
Speakers Series in Economics<br />
JAMES BULLARD<br />
Former CEO and 12th President of Federal Reserve Bank of St. Louis<br />
On April 2, <strong>2024</strong>, the Economics Department was pleased to have former St. Louis Fed<br />
CEO & President Jim Bullard deliver a public talk on a question that is on many peoples’<br />
mind: Can the Fed Stick the Soft Landing? Bullard argued that relative to a famous<br />
protocol for setting interest rates (known as the Taylor Rule), the Fed was too late in<br />
raising its policy rate in 2021 and is now too slow in cutting its policy rate in <strong>2024</strong>.<br />
Overly tight monetary conditions increase the risk of policy-induced recession, turning<br />
the soft-landing into a hard-landing. A lively Q&A followed his talk.<br />

COUNCIL OF THE<br />
AMERICAS<br />
PROFESSOR RICARDO LAGO<br />
On December 15, Professor Ricardo Lago<br />
gave the keynote address to the annual CFO<br />
meeting of the Council of the Americas. The<br />
topic was “USA and Latin America in the<br />
unfolding world economic outlook.”<br />
Forecasters had predicted that the inflation<br />
fight would tip the U.S. economy into<br />
recession. But as in Samuel Beckett’s<br />
“Waiting for Godot” there is no sign of it yet.<br />
In the rest of the world, however, economies<br />
are in general not faring well. Only India and<br />
Brazil show some dynamism. Moreover,<br />
financial and geopolitical risks tilt forecasts to<br />
the downside.
7th Annual CSO Summit &<br />
Symposium<br />
By: Dr. Daniel Hicks<br />
The 7th Annual Chief Sustainability Officer Summit<br />
& Symposium (CSOSS), presented by Calamos<br />
Investments, addressed topics associated with<br />
global reporting aligned, ESG investing and<br />
sustainable real estate.<br />
A summit of chief sustainability officers highlights<br />
the morning sessions. CSOSS is hosted by Miami<br />
Herbert Business School and the Department of<br />
Economics, in partnership with the University of<br />
Miami’s Rosenstiel School of Marine, Atmospheric,<br />
and Earth Science and the College of Engineering.<br />
Florida’s premier networking event in sustainable<br />
business.<br />
CSOSS attracts corporate executives from every<br />
economic sector, sustainability professionals from across<br />
industries, investment managers, government<br />
policymakers, NGO and community leaders, distinguished<br />
researchers and international students from a range of<br />
academic disciplines.<br />
CSOSS organizers want to thank its generous sponsors,<br />
Calamos Investments and Universal Insurance Holdings,<br />
Inc. for their support.<br />
The theme of the conference is "Building Consensus in an<br />
Election Year.” The event was held on April 5 at the<br />
university’s new Lakeside Auditorium & Pavilion in Coral<br />
Gables, Florida.

PROFESSOR IRAOLA TRAVELS TO<br />
SPAIN WITH 29 STUDENTS<br />
Globe <strong>2024</strong> program in Spain, March 3-12, <strong>2024</strong><br />
As part of the Globe <strong>2024</strong> program, last spring break Dr. Miguel A.<br />
Iraola led an experiential learning course in Spain. Twenty-nine<br />
Miami Herbert Business School graduate students (mainly from the<br />
Master of International Business) participated in this program<br />
visiting Madrid and Barcelona for nine days. Students were able to<br />
immerse in the Spanish culture and deepen their knowledge of<br />
main economic challenges and opportunities in Spain. The program<br />
included several cultural activities and visits to historic sites. For<br />
instance, the students attended a flamenco show and visited<br />
emblematic historic sites like the Madrid City Hall, Sagrada Familia<br />
in Barcelona, and Bodegas Codorníu, a winery with over 400 years<br />
of experience.<br />
The academic part of the program involved company visits and<br />
presentations covering various economic sectors, including<br />
finance, retail, consulting, professional soccer, and the food<br />
industry. One of the most successful activities was the meeting<br />
with Sheila Boudount and Pau Aragay from Marinva. This is a<br />
Barcelona based company specialized in the use of games for<br />
trainings and the transformation of teams and organizations. The<br />
students had the opportunity of participating in several games<br />
highlighting the potential of play-based trainings.

An interpretation of events 1951-2019<br />
From the Treasury-Fed accord in 1951 up to the early 1960s, federal government<br />
deficits remained low and monetary policy remained relatively tight. Persistent peacetime<br />
budget deficits first appeared during the Kennedy-Johnson administrations in the<br />
early 1960 and proceeded unabated until the Clinton surpluses in late 1990s. A<br />
relatively loose monetary-fiscal policy mix combined with two severe oil price shocks in<br />
1973-74, 1979-80 conspired to produce secular inflation.<br />
In response to high and persistent inflation, the Federal Reserve tightened monetary<br />
policy which, together with an oil price shock associated with the Iran-Iraq war, produced<br />
a severe recessionary episode from 1980-82. The recession along with President<br />
Reagan’s famous 1981 tax cut produced ever larger fiscal deficits fueled, in part, by the<br />
Fed’s high interest rate policy.<br />
The following figure shows the rate of growth of the U.S. federal debt. Note how the<br />
pace of issuance accelerates in the 1960s and then decelerates in the 1980s and<br />
1990s. This pattern roughly tracks the secular rise and fall in the interest rate, displayed<br />
in Figure 1.<br />
