                            ------------------------
 
     This statement is furnished by the Board of Directors of The Morgan Stanley
High Yield Fund, Inc. (the "Fund") in connection with the solicitation of
Proxies by the Board of Directors for use at the Annual Meeting of Stockholders
(the "Meeting") to be held on Monday, June 21, 1999 at 11:00 a.m. (New York

Dean Witter Investment Management Inc. (hereinafter "MSDW Investment Management"
or the "Manager"), 1221 Avenue of the Americas, 22nd Floor, New York, New York
10020. It is expected that the Notice of Annual Meeting, Proxy Statement and
form of Proxy will first be mailed to stockholders on or about May 14, 1999. The
purpose of the Meeting and the matters to be acted upon are set forth in the
accompanying Notice of Annual Meeting of Stockholders.
 
     If the accompanying form of Proxy is executed properly and returned, shares
represented by it will be voted at the Meeting in accordance with the
instructions on the Proxy. A Proxy may be revoked at any time prior to the time
it is voted by written notice to the Secretary of the Fund or by attendance and
voting at the Meeting. If no instructions are specified, shares will be voted
FOR the election of the nominees for Directors, FOR ratification of
PricewaterhouseCoopers LLP as independent accountants of the Fund for the fiscal
year ending December 31, 1999 and FOR approval of the amendment to the Fund's
Articles of Incorporation to change the name of the Fund.
 
     The Board has fixed the close of business on April 15, 1999 as the record
date for the determination of stockholders entitled to notice of, and to vote
at, the Meeting and at any adjournment thereof. On that date, the Fund had
8,832,863 shares of Common Stock outstanding and entitled to vote. Each share
will be entitled to one vote at the Meeting.
 
     The expense of solicitation will be borne by the Fund and will include
reimbursement to brokerage firms and others for expenses in forwarding proxy
solicitation materials to beneficial owners. The solicitation of Proxies will be
largely by mail, but may include, without cost to the Fund, telephonic,
telegraphic or oral communications by regular employees of the Manager. The
solicitation of Proxies is also expected to include communications by employees
of Shareholder Communications Corporation, a proxy solicitation firm expected to
be engaged by the Fund at a cost not expected to exceed $5,000, plus
out-of-pocket expenses.
 
     THE FUND WILL FURNISH, WITHOUT CHARGE, A COPY OF ITS ANNUAL REPORT FOR ITS
FISCAL YEAR ENDED DECEMBER 31, 1998, TO ANY STOCKHOLDER REQUESTING SUCH REPORT.
REQUESTS FOR THE ANNUAL REPORT SHOULD BE MADE IN WRITING TO THE MORGAN STANLEY

                             ELECTION OF DIRECTORS
                                (PROPOSAL NO. 1)
 
     At the Meeting, three Directors will be elected to hold office for a term
of three years and until their successors are duly elected and qualified. It is
the intention of the persons named in the accompanying form of Proxy to vote, on
behalf of the stockholders, for the election of Peter J. Chase, David B. Gill
and Michael F. Klein as Class I Directors.
 
     Pursuant to the Fund's By-Laws, the terms of office of the Directors are
staggered. The Board of Directors is divided into three classes, designated
Class I, Class II and Class III, with each class having a term of three years.
Each year the term of one class expires. Class I currently consists of Peter J.
Chase, David B. Gill and Michael F. Klein. Class II currently consists of John
W. Croghan and Graham E. Jones. Class III currently consists of Barton M. Biggs,
John A. Levin and William G. Morton, Jr. Only the Directors in Class I are being
considered for election at this Meeting.
 
     Pursuant to the Fund's By-Laws, each Director holds office until (i) the
expiration of his term and until his successor has been elected and qualified,
(ii) his death, (iii) his resignation, (iv) December 31 of the year in which he
reaches seventy-three years of age, or (v) his removal as provided by statute or
the Articles of Incorporation.
 
     The Board of Directors has an Audit Committee. The Audit Committee makes
recommendations to the full Board of Directors with respect to the engagement of
independent accountants and reviews with the independent accountants the plan
and results of the audit engagement and matters having a material effect on the
Fund's financial operations. The members of the Audit Committee are currently
Peter J. Chase, David B. Gill and Graham E. Jones, none of whom is an
"interested person," as defined under the Investment Company Act of 1940, as
amended (the "1940 Act"). The Chairman of the Audit Committee is Mr. Jones. The
Audit Committee met two times during the fiscal year ended December 31, 1998.
The Board of Directors does not have nominating or compensation committees or
other committees performing similar functions.
 
     There were four meetings of the Board of Directors held during the fiscal
year ended December 31, 1998. For the fiscal year ended December 31, 1998, each
current Director attended at least seventy-five percent of the aggregate number
of meetings of the Board and of any committee on which he served.
 
     Each of the nominees for Director has consented to be named in this Proxy
Statement and to serve as a director of the Fund if elected. The Board of
Directors has no reason to believe that any of the nominees named above will
become unavailable for election as a director, but if that should occur before
the Meeting, Proxies will be voted for such persons as the Board of Directors
may recommend.

  *  "Interested person" within the meaning of the 1940 Act. Mr.
     Biggs is chairman, director and managing director of the
     Manager, and Messrs. Klein, Schaaff and Stadler and Ms.
     Chang are officers of the Manager.
 **  This information has been furnished by each nominee,
     director and officer.
***  Less than 1%.
  +  Indicates share equivalents owned by the Directors and held
     in cash accounts by the Fund on behalf of the Directors in
     connection with the deferred fee arrangements described
     below.

 
     Each officer of the Fund will hold such office until a successor has been
duly elected and qualified.

     The Fund pays each of its Directors who is not a director, officer or
employee of MSDW Investment Management or its affiliates an annual fee of
$4,795, plus out-of-pocket expenses. Each of the members of the Fund's Audit
Committee, which consists of the Fund's Directors who are not "interested
persons" of the Fund as defined in the 1940 Act, will receive an additional fee
of $787 for serving on such committee.
 
     Each of the Directors who is not an "affiliated person" of MSDW Investment
Management within the meaning of the 1940 Act may enter into a deferred fee
arrangement (the "Fee Arrangement") with the Fund, pursuant to which such
Director may defer to a later date the receipt of his Director's fees. The
deferred fees owed by the Fund are credited to a bookkeeping account maintained
by the Fund on behalf of such Director and accrue income from and after the date
of credit in an amount equal to the amount that would have been earned had such
fees (and all income earned thereon) been invested and reinvested either (i) in
shares of the Fund or (ii) at a rate equal to the prevailing rate applicable to
90-day United States Treasury Bills at the beginning of each calendar quarter
for which this rate is in effect, whichever method is elected by the Director.
 
     Under the Fee Arrangement, deferred Director's fees (including the return
accrued thereon) will become payable in cash upon such Director's resignation
from the Board of Directors in generally equal annual installments over a period
of five years (unless the Fund has agreed to a longer or shorter payment period)
beginning on the first day of the year following the year in which such
Director's resignation occurred. In the event of a Director's death, remaining
amounts payable to him under the Fee Arrangement will thereafter be payable to
his designated beneficiary; in all other events, a Director's right to receive
payments is non-transferable. Under the Fee Arrangement, the Board of Directors
of the Fund, in its sole discretion, has reserved the right, at the request of a
Director or otherwise, to accelerate or extend the payment of amounts in the
deferred fee account at any time after the termination of such Director's
service as a director. In addition, in the event of liquidation, dissolution or
winding up of the Fund or the distribution of all or substantially all of the
Fund's assets and property to its stockholders (other than in connection with a
reorganization or merger into another fund advised by MSDW Investment
Management), all unpaid amounts in the deferred fee account maintained by the
Fund will be paid in a lump sum to the Directors participating in the Fee
Arrangement on the effective date thereof.
 
     Set forth below is a table showing the aggregate compensation paid by the
Fund to each of its Directors, as well as the total compensation paid to each
Director of the Fund by the Fund and by other U.S. registered investment
companies advised by MSDW Investment Management or its affiliates (collectively,
the "Fund Complex") for their services as Directors of such investment companies
for the fiscal year ended December 31, 1998.

"Exchange Act"), requires the Fund's officers and directors, and persons who own
more than ten percent of a registered class of the Fund's equity securities, to
file reports of ownership and changes in ownership with the Securities and
Exchange Commission (the "Commission") and the New York Stock Exchange, Inc. The

and directors and believes that all required reports under Section 16(a) have
been filed on a timely basis for the Fund's officers and directors.
 
     The election of Messrs. Chase, Gill and Klein requires the affirmative vote
of a majority of the votes cast at a meeting at which a quorum is present. Under
the Fund's By-Laws, the presence in person or by proxy of stockholders entitled
to cast a majority of the votes entitled to be cast thereat shall constitute a
quorum. For this purpose, abstentions and broker non-votes will be counted in
determining whether a quorum is present at the Meeting, but will not be counted

                      SELECTION OF INDEPENDENT ACCOUNTANTS
                                (PROPOSAL NO. 2)
 
     The Board of Directors of the Fund, including a majority of the Directors
who are not "interested persons" of the Fund as defined in the 1940 Act, has
selected PricewaterhouseCoopers LLP as independent accountants for the Fund for
the fiscal year ending December 31, 1999. The ratification of the selection of
independent accountants is to be voted on at the Meeting, and it is intended
that the persons named in the accompanying Proxy will vote for ratification of
PricewaterhouseCoopers LLP's appointment. PricewaterhouseCoopers LLP acts as the
independent accountants for certain of the other investment companies advised by
MSDW Investment Management. Although it is not expected that a representative of
PricewaterhouseCoopers LLP will attend the Meeting, a representative will be
available by telephone to respond to stockholder questions, if any.
 
     The Board's policy regarding engaging independent accountants' services is
that management may engage the Fund's principal independent accountants to
perform any services normally provided by independent accounting firms, provided
that such services meet any and all of the independence requirements of the
American Institute of Certified Public Accountants and the Securities and
Exchange Commission. In accordance with this policy, the Audit Committee reviews
and approves all services provided by the independent accountants prior to their
being rendered. The Board of Directors also receives a report from its Audit
Committee relating to all services that have been performed by the Fund's
independent accountants.
 
     The ratification of the selection of independent accountants requires the
affirmative vote of a majority of the votes cast at a meeting at which a quorum
is present. For this purpose, abstentions and broker non-votes will be counted
in determining whether a quorum is present at the Meeting, but will not be
counted as votes cast at the Meeting.
 
     THE BOARD OF DIRECTORS OF THE FUND RECOMMENDS THAT YOU VOTE "FOR" THIS
PROPOSAL NO. 2.
 
                        APPROVAL OF AN AMENDMENT TO THE
                        FUND'S ARTICLES OF INCORPORATION
                                (PROPOSAL NO. 3)
 
     The Board of Directors has approved an amendment to the Fund's Articles of
Incorporation to change the name of the Fund to Morgan Stanley Dean Witter High
Yield Fund, Inc. The Board determined that the name change was necessary and
appropriate in light of the merger between Morgan Stanley Group Inc. and Dean
Witter, Discover & Co. effective May 31, 1998.
 
     Approval of the proposed name change will require the affirmative vote of a
majority of the total number of shares of Common Stock of the Fund outstanding
and entitled to vote. For this purpose, abstentions and broker non-votes will be
counted in determining whether a quorum is present at the Meeting, but will not
count towards achieving the required majority vote.
 
     THE BOARD OF DIRECTORS OF THE FUND RECOMMENDS THAT YOU VOTE "FOR" THIS
PROPOSAL NO. 3.
